# vim:fileencoding=utf-8:foldmethod=marker
#: Fonts {{{
#: kitty has very powerful font management. You can configure
#: individual font faces and even specify special fonts for particular
#: characters.
font_family Menlo
# bold_font auto
# italic_font auto
# bold_italic_font auto
#: You can specify different fonts for the bold/italic/bold-italic
#: variants. To get a full list of supported fonts use the `kitty
#: list-fonts` command. By default they are derived automatically, by
#: the OSes font system. When bold_font or bold_italic_font is set to
#: auto on macOS, the priority of bold fonts is semi-bold, bold,
#: heavy. Setting them manually is useful for font families that have
#: many weight variants like Book, Medium, Thick, etc. For example::
#: font_family Operator Mono Book
#: bold_font Operator Mono Medium
#: italic_font Operator Mono Book Italic
#: bold_italic_font Operator Mono Medium Italic
font_size 14.0
#: Font size (in pts)
# force_ltr no
#: kitty does not support BIDI (bidirectional text), however, for RTL
#: scripts, words are automatically displayed in RTL. That is to say,
#: in an RTL script, the words "HELLO WORLD" display in kitty as
#: "WORLD HELLO", and if you try to select a substring of an RTL-
#: shaped string, you will get the character that would be there had
#: the the string been LTR. For example, assuming the Hebrew word
#: ירושלים, selecting the character that on the screen appears to be ם
#: actually writes into the selection buffer the character י. kitty's
#: default behavior is useful in conjunction with a filter to reverse
#: the word order, however, if you wish to manipulate RTL glyphs, it
#: can be very challenging to work with, so this option is provided to
#: turn it off. Furthermore, this option can be used with the command
#: line program GNU FriBidi
#: to get BIDI
#: support, because it will force kitty to always treat the text as
#: LTR, which FriBidi expects for terminals.
# adjust_line_height 0
# adjust_column_width 0
#: Change the size of each character cell kitty renders. You can use
#: either numbers, which are interpreted as pixels or percentages
#: (number followed by %), which are interpreted as percentages of the
#: unmodified values. You can use negative pixels or percentages less
#: than 100% to reduce sizes (but this might cause rendering
#: artifacts).
# adjust_baseline 0
#: Adjust the vertical alignment of text (the height in the cell at
#: which text is positioned). You can use either numbers, which are
#: interpreted as pixels or a percentages (number followed by %),
#: which are interpreted as the percentage of the line height. A
#: positive value moves the baseline up, and a negative value moves
#: them down. The underline and strikethrough positions are adjusted
#: accordingly.
# symbol_map
#: E.g. symbol_map U+E0A0-U+E0A3,U+E0C0-U+E0C7 PowerlineSymbols
#: Map the specified unicode codepoints to a particular font. Useful
#: if you need special rendering for some symbols, such as for
#: Powerline. Avoids the need for patched fonts. Each unicode code
#: point is specified in the form U+. You
#: can specify multiple code points, separated by commas and ranges
#: separated by hyphens. symbol_map itself can be specified multiple
#: times. Syntax is::
#: symbol_map codepoints Font Family Name
# disable_ligatures never
#: Choose how you want to handle multi-character ligatures. The
#: default is to always render them. You can tell kitty to not render
#: them when the cursor is over them by using cursor to make editing
#: easier, or have kitty never render them at all by using always, if
#: you don't like them. The ligature strategy can be set per-window
#: either using the kitty remote control facility or by defining
#: shortcuts for it in kitty.conf, for example::
#: map alt+1 disable_ligatures_in active always
#: map alt+2 disable_ligatures_in all never
#: map alt+3 disable_ligatures_in tab cursor
#: Note that this refers to programming ligatures, typically
#: implemented using the calt OpenType feature. For disabling general
#: ligatures, use the font_features setting.
# font_features
#: E.g. font_features none
#: Choose exactly which OpenType features to enable or disable. This
#: is useful as some fonts might have features worthwhile in a
#: terminal. For example, Fira Code Retina includes a discretionary
#: feature, zero, which in that font changes the appearance of the
#: zero (0), to make it more easily distinguishable from Ø. Fira Code
#: Retina also includes other discretionary features known as
#: Stylistic Sets which have the tags ss01 through ss20.
#: For the exact syntax to use for individual features, see the
#: Harfbuzz documentation .
#: Note that this code is indexed by PostScript name, and not the font
#: family. This allows you to define very precise feature settings;
#: e.g. you can disable a feature in the italic font but not in the
#: regular font.
#: On Linux, these are read from the FontConfig database first and
#: then this, setting is applied, so they can be configured in a
#: single, central place.
#: To get the PostScript name for a font, use kitty + list-fonts
#: --psnames:
#: .. code-block:: sh
#: $ kitty + list-fonts --psnames | grep Fira
#: Fira Code
#: Fira Code Bold (FiraCode-Bold)
#: Fira Code Light (FiraCode-Light)
#: Fira Code Medium (FiraCode-Medium)
#: Fira Code Regular (FiraCode-Regular)
#: Fira Code Retina (FiraCode-Retina)
#: The part in brackets is the PostScript name.
#: Enable alternate zero and oldstyle numerals::
#: font_features FiraCode-Retina +zero +onum
#: Enable only alternate zero::
#: font_features FiraCode-Retina +zero
#: Disable the normal ligatures, but keep the calt feature which (in
#: this font) breaks up monotony::
#: font_features TT2020StyleB-Regular -liga +calt
#: In conjunction with force_ltr, you may want to disable Arabic
#: shaping entirely, and only look at their isolated forms if they
#: show up in a document. You can do this with e.g.::
#: font_features UnifontMedium +isol -medi -fina -init
# box_drawing_scale 0.001, 1, 1.5, 2
#: Change the sizes of the lines used for the box drawing unicode
#: characters These values are in pts. They will be scaled by the
#: monitor DPI to arrive at a pixel value. There must be four values
#: corresponding to thin, normal, thick, and very thick lines.
#: }}}
#: Cursor customization {{{
cursor #81b400
#: Default cursor color. If set to the special value none the cursor
#: will be rendered with a "reverse video" effect. It's color will be
#: the color of the text in the cell it is over and the text will be
#: rendered with the background color of the cell. Note that if the
#: program running in the terminal sets a cursor color, this takes
#: precedence. Also, the cursor colors are modified if the cell
#: background and foreground colors have very low contrast.
# cursor_text_color #111111
#: Choose the color of text under the cursor. If you want it rendered
#: with the background color of the cell underneath instead, use the
#: special keyword: background. Note that if cursor is set to none
#: then this setting is ignored.
cursor_shape block
#: The cursor shape can be one of (block, beam, underline). Note that
#: when reloading the config this will be changed only if the cursor
#: shape has not been set by the program running in the terminal. This
#: sets the default cursor shape. Applications running in the terminal
#: can override it. In particular,
#: https://sw.kovidgoyal.net/kitty/shell-integration/ in kitty sets
#: the cursor shape to beam at shell prompts. You can avoid this by
#: setting shell_integration to no-cursor.
# cursor_beam_thickness 1.5
#: Defines the thickness of the beam cursor (in pts)
# cursor_underline_thickness 2.0
#: Defines the thickness of the underline cursor (in pts)
cursor_blink_interval 0.20
#: The interval (in seconds) at which to blink the cursor. Set to zero
#: to disable blinking. Negative values mean use system default. Note
#: that numbers smaller than repaint_delay will be limited to
#: repaint_delay.
cursor_stop_blinking_after 1.0
#: Stop blinking cursor after the specified number of seconds of
#: keyboard inactivity. Set to zero to never stop blinking.
#: }}}
#: Scrollback {{{
scrollback_lines 2000000
#: Number of lines of history to keep in memory for scrolling back.
#: Memory is allocated on demand. Negative numbers are (effectively)
#: infinite scrollback. Note that using very large scrollback is not
#: recommended as it can slow down performance of the terminal and
#: also use large amounts of RAM. Instead, consider using
#: scrollback_pager_history_size. Note that on config reload if this
#: is changed it will only affect newly created windows, not existing
#: ones.
# scrollback_pager less --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER
#: Program with which to view scrollback in a new window. The
#: scrollback buffer is passed as STDIN to this program. If you change
#: it, make sure the program you use can handle ANSI escape sequences
#: for colors and text formatting. INPUT_LINE_NUMBER in the command
#: line above will be replaced by an integer representing which line
#: should be at the top of the screen. Similarly CURSOR_LINE and
#: CURSOR_COLUMN will be replaced by the current cursor position or
#: set to 0 if there is no cursor, for example, when showing the last
#: command output.
# scrollback_pager_history_size 0
#: Separate scrollback history size, used only for browsing the
#: scrollback buffer (in MB). This separate buffer is not available
#: for interactive scrolling but will be piped to the pager program
#: when viewing scrollback buffer in a separate window. The current
#: implementation stores the data in UTF-8, so approximatively 10000
#: lines per megabyte at 100 chars per line, for pure ASCII text,
#: unformatted text. A value of zero or less disables this feature.
#: The maximum allowed size is 4GB. Note that on config reload if this
#: is changed it will only affect newly created windows, not existing
#: ones.
# scrollback_fill_enlarged_window no
#: Fill new space with lines from the scrollback buffer after
#: enlarging a window.
# wheel_scroll_multiplier 5.0
#: Modify the amount scrolled by the mouse wheel. Note this is only
#: used for low precision scrolling devices, not for high precision
#: scrolling on platforms such as macOS and Wayland. Use negative
#: numbers to change scroll direction.
# touch_scroll_multiplier 1.0
#: Modify the amount scrolled by a touchpad. Note this is only used
#: for high precision scrolling devices on platforms such as macOS and
#: Wayland. Use negative numbers to change scroll direction.
#: }}}
#: Mouse {{{
# mouse_hide_wait 3.0
#: Hide mouse cursor after the specified number of seconds of the
#: mouse not being used. Set to zero to disable mouse cursor hiding.
#: Set to a negative value to hide the mouse cursor immediately when
#: typing text. Disabled by default on macOS as getting it to work
#: robustly with the ever-changing sea of bugs that is Cocoa is too
#: much effort.
# url_color #0087bd
url_style double
#: The color and style for highlighting URLs on mouse-over. url_style
#: can be one of: none, straight, double, curly, dotted, dashed
# open_url_with default
#: The program with which to open URLs that are clicked on. The
#: special value default means to use the operating system's default
#: URL handler (open on macOS and xdg-open on Linux).
# url_prefixes http https file ftp gemini irc gopher mailto news git
#: The set of URL prefixes to look for when detecting a URL under the
#: mouse cursor.
# detect_urls yes
#: Detect URLs under the mouse. Detected URLs are highlighted with an
#: underline and the mouse cursor becomes a hand over them. Even if
#: this option is disabled, URLs are still clickable.
# url_excluded_characters
#: Additional characters to be disallowed from URLs, when detecting
#: URLs under the mouse cursor. By default, all characters legal in
#: URLs are allowed.
# copy_on_select no
#: Copy to clipboard or a private buffer on select. With this set to
#: clipboard, simply selecting text with the mouse will cause the text
#: to be copied to clipboard. Useful on platforms such as macOS that
#: do not have the concept of primary selections. You can instead
#: specify a name such as a1 to copy to a private kitty buffer
#: instead. Map a shortcut with the paste_from_buffer action to paste
#: from this private buffer. For example::
#: map shift+cmd+v paste_from_buffer a1
#: Note that copying to the clipboard is a security risk, as all
#: programs, including websites open in your browser can read the
#: contents of the system clipboard.
# strip_trailing_spaces never
#: Remove spaces at the end of lines when copying to clipboard. A
#: value of smart will do it when using normal selections, but not
#: rectangle selections. always will always do it.
# select_by_word_characters @-./_~?&=%+#
#: Characters considered part of a word when double clicking. In
#: addition to these characters any character that is marked as an
#: alphanumeric character in the unicode database will be matched.
# click_interval -1.0
#: The interval between successive clicks to detect double/triple
#: clicks (in seconds). Negative numbers will use the system default
#: instead, if available, or fallback to 0.5.
# focus_follows_mouse no
#: Set the active window to the window under the mouse when moving the
#: mouse around
# pointer_shape_when_grabbed arrow
#: The shape of the mouse pointer when the program running in the
#: terminal grabs the mouse. Valid values are: arrow, beam and hand
# default_pointer_shape beam
#: The default shape of the mouse pointer. Valid values are: arrow,
#: beam and hand
# pointer_shape_when_dragging beam
#: The default shape of the mouse pointer when dragging across text.
#: Valid values are: arrow, beam and hand
#: Mouse actions {{{
#: Mouse buttons can be remapped to perform arbitrary actions. The
#: syntax for doing so is:
#: .. code-block:: none
#: mouse_map button-name event-type modes action
#: Where ``button-name`` is one of ``left``, ``middle``, ``right`` or
#: ``b1 ... b8`` with added keyboard modifiers, for example:
#: ``ctrl+shift+left`` refers to holding the ctrl+shift keys while
#: clicking with the left mouse button. The number ``b1 ... b8`` can
#: be used to refer to upto eight buttons on a mouse.
#: ``event-type`` is one ``press``, ``release``, ``doublepress``,
#: ``triplepress``, ``click`` and ``doubleclick``. ``modes``
#: indicates whether the action is performed when the mouse is grabbed
#: by the program running in the terminal, or not. It can have one or
#: more or the values, ``grabbed,ungrabbed``. ``grabbed`` refers to
#: when the program running in the terminal has requested mouse
#: events. Note that the click and double click events have a delay of
#: click_interval to disambiguate from double and triple presses.
#: You can run kitty with the kitty --debug-input command line option
#: to see mouse events. See the builtin actions below to get a sense
#: of what is possible.
#: If you want to unmap an action map it to ``no-op``. For example, to
#: disable opening of URLs with a plain click::
#: mouse_map left click ungrabbed no-op
#: .. note::
#: Once a selection is started, releasing the button that started it will
#: automatically end it and no release event will be dispatched.
# clear_all_mouse_actions no
#: You can have kitty remove all mouse actions seen up to this point.
#: Useful, for instance, to remove the default mouse actions.
#: Click the link under the mouse or move the cursor
# mouse_map left click ungrabbed mouse_handle_click selection link prompt
#:: First check for a selection and if one exists do nothing. Then
#:: check for a link under the mouse cursor and if one exists, click
#:: it. Finally check if the click happened at the current shell
#:: prompt and if so, move the cursor to the click location. Note
#:: that this requires shell-integration to work.
#: Click the link under the mouse or move the cursor even when grabbed
# mouse_map shift+left click grabbed,ungrabbed mouse_handle_click selection link prompt
#:: Same as above, except that the action is performed even when the
#:: mouse is grabbed by the program running in the terminal.
#: Click the link under the mouse cursor
# mouse_map ctrl+shift+left release grabbed,ungrabbed mouse_handle_click link

#: }}}
#: Performance tuning {{{
# repaint_delay 10
#: Delay (in milliseconds) between screen updates. Decreasing it,
#: increases frames-per-second (FPS) at the cost of more CPU usage.
#: The default value yields ~100 FPS which is more than sufficient for
#: most uses. Note that to actually achieve 100 FPS you have to either
#: set sync_to_monitor to no or use a monitor with a high refresh
#: rate. Also, to minimize latency when there is pending input to be
#: processed, repaint_delay is ignored.
# input_delay 3
#: Delay (in milliseconds) before input from the program running in
#: the terminal is processed. Note that decreasing it will increase
#: responsiveness, but also increase CPU usage and might cause flicker
#: in full screen programs that redraw the entire screen on each loop,
#: because kitty is so fast that partial screen updates will be drawn.
# sync_to_monitor yes
#: Sync screen updates to the refresh rate of the monitor. This
#: prevents tearing (https://en.wikipedia.org/wiki/Screen_tearing)
#: when scrolling. However, it limits the rendering speed to the
#: refresh rate of your monitor. With a very high speed mouse/high
#: keyboard repeat rate, you may notice some slight input latency. If
#: so, set this to no.
#: }}}
#: Terminal bell {{{
enable_audio_bell no
#: Enable/disable the audio bell. Useful in environments that require
#: silence.
visual_bell_duration 0.1
#: Visual bell duration. Flash the screen when a bell occurs for the
#: specified number of seconds. Set to zero to disable.
visual_bell_color #110088
#: The color used by visual bell. Set to none will fall back to
#: selection background color. If you feel that the visual bell is too
#: bright, you can set it to a darker color.
# window_alert_on_bell yes
#: Request window attention on bell. Makes the dock icon bounce on
#: macOS or the taskbar flash on linux.
# bell_on_tab "🔔 "
#: Some text or a unicode symbol to show on the tab if a window in the
#: tab that does not have focus has a bell. If you want to use leading
#: or trailing spaces surround the text with quotes. See
#: tab_title_template for how this is rendered.
#: For backwards compatibility, values of yes, y, true are converted
#: to the default bell symbol and no, n, false, none are converted to
#: the empty string.
# command_on_bell none
#: Program to run when a bell occurs. The environment variable
#: KITTY_CHILD_CMDLINE can be used to get the program running in the
#: window in which the bell occurred.
# bell_path none
#: Path to a sound file to play as the bell sound. If set to none, the
#: system default bell sound is used. Must be in a format supported by
#: the operating systems sound API, such as WAV or OGA on Linux
#: (libcanberra) or AIFF, MP3 or WAV on macOS (NSSound)
#: }}}
#: Window layout {{{
# remember_window_size yes
# initial_window_width 640
# initial_window_height 400
#: If enabled, the window size will be remembered so that new
#: instances of kitty will have the same size as the previous
#: instance. If disabled, the window will initially have size
#: configured by initial_window_width/height, in pixels. You can use a
#: suffix of "c" on the width/height values to have them interpreted
#: as number of cells instead of pixels.
# enabled_layouts *
#: The enabled window layouts. A comma separated list of layout names.
#: The special value all means all layouts. The first listed layout
#: will be used as the startup layout. Default configuration is all
#: layouts in alphabetical order. For a list of available layouts, see
#: the https://sw.kovidgoyal.net/kitty/overview/#layouts.
# window_resize_step_cells 2
# window_resize_step_lines 2
#: The step size (in units of cell width/cell height) to use when
#: resizing kitty windows in a layout with the keyboard
#: (start_resizing_window). The cells value is used for horizontal
#: resizing and the lines value for vertical resizing.
# window_border_width 0.5pt
#: The width of window borders. Can be either in pixels (px) or pts
#: (pt). Values in pts will be rounded to the nearest number of pixels
#: based on screen resolution. If not specified the unit is assumed to
#: be pts. Note that borders are displayed only when more than one
#: window is visible. They are meant to separate multiple windows.
# draw_minimal_borders yes
#: Draw only the minimum borders needed. This means that only the
#: minimum needed borders for inactive windows are drawn. That is only
#: the borders that separate the inactive window from a neighbor. Note
#: that setting a non-zero window margin overrides this and causes all
#: borders to be drawn.
# window_margin_width 0
#: The window margin (in pts) (blank area outside the border). A
#: single value sets all four sides. Two values set the vertical and
#: horizontal sides. Three values set top, horizontal and bottom. Four
#: values set top, right, bottom and left.
# single_window_margin_width -1
#: The window margin (in pts) to use when only a single window is
#: visible. Negative values will cause the value of
#: window_margin_width to be used instead. A single value sets all
#: four sides. Two values set the vertical and horizontal sides. Three
#: values set top, horizontal and bottom. Four values set top, right,
#: bottom and left.
# window_padding_width 0
#: The window padding (in pts) (blank area between the text and the
#: window border). A single value sets all four sides. Two values set
#: the vertical and horizontal sides. Three values set top, horizontal
#: and bottom. Four values set top, right, bottom and left.
# placement_strategy center
#: When the window size is not an exact multiple of the cell size, the
#: cell area of the terminal window will have some extra padding on
#: the sides. You can control how that padding is distributed with
#: this option. Using a value of center means the cell area will be
#: placed centrally. A value of top-left means the padding will be on
#: only the bottom and right edges.
# active_border_color #00ff00
#: The color for the border of the active window. Set this to none to
#: not draw borders around the active window.
# inactive_border_color #cccccc
#: The color for the border of inactive windows
# bell_border_color #ff5a00
#: The color for the border of inactive windows in which a bell has
#: occurred
# inactive_text_alpha 1.0
#: Fade the text in inactive windows by the specified amount (a number
#: between zero and one, with zero being fully faded).
# hide_window_decorations no
#: Hide the window decorations (title-bar and window borders) with
#: yes. On macOS, titlebar-only can be used to only hide the titlebar.
#: Whether this works and exactly what effect it has depends on the
#: window manager/operating system. Note that the effects of changing
#: this setting when reloading config are undefined.
# window_logo_path none
#: Path to a logo image. Must be in PNG format. Relative paths are
#: interpreted relative to the kitty config directory. The logo is
#: displayed in a corner of every kitty window. The position is
#: controlled by window_logo_position. Individual windows can be
#: configured to have different logos either using the launch function
#: or the remote-control facility.
# window_logo_position bottom-right
#: Where to position the window logo in the window. The value can be
#: one of: top-left, top, top-right, left, center, right, bottom-left,
#: bottom, bottom-right.
# window_logo_alpha 0.5
#: The amount the logo should be faded into the background. With zero
#: being fully faded and one being fully opaque.
# resize_debounce_time 0.1
#: The time (in seconds) to wait before redrawing the screen when a
#: resize event is received. On platforms such as macOS, where the
#: operating system sends events corresponding to the start and end of
#: a resize, this number is ignored.
# resize_draw_strategy static
#: Choose how kitty draws a window while a resize is in progress. A
#: value of static means draw the current window contents, mostly
#: unchanged. A value of scale means draw the current window contents
#: scaled. A value of blank means draw a blank window. A value of size
#: means show the window size in cells.
# resize_in_steps no
#: Resize the OS window in steps as large as the cells, instead of
#: with the usual pixel accuracy. Combined with an
#: initial_window_width and initial_window_height in number of cells,
#: this option can be used to keep the margins as small as possible
#: when resizing the OS window. Note that this does not currently work
#: on Wayland.
# visual_window_select_characters 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
#: The list of characters to use for visual window selection (for
#: example for selecting a window to focus with focus_visible_window).
#: The value should be a series of unique numbers or alphabets, case
#: insensitive, from the set [0-9A-Z]. Specify your preference as a
#: string of characters.
# confirm_os_window_close 0
#: Ask for confirmation when closing an OS window or a Tab with at
#: least this number of kitty windows in it by window manager (e.g.
#: clicking the window close button or pressing the Operating system
#: shortcut to close windows) or by the close_tab action. A value of
#: zero disables confirmation. This confirmation also applies to
#: requests to quit the entire application (all OS windows, via the
#: quit action). Negative values are converted to positive ones,
#: however, with https://sw.kovidgoyal.net/kitty/shell-integration/
#: enabled, using negative values means windows sitting at a shell
#: prompt are not counted, only windows where some command is
#: currently running. Note that if you want confirmation when closing
#: individual windows, you can map the
#: https://sw.kovidgoyal.net/kitty/actions/#close-window-with-

#: center, or right.
tab_bar_min_tabs 1
#: The minimum number of tabs that must exist before the tab bar is
#: shown
# tab_switch_strategy previous
#: The algorithm to use when switching to a tab when the current tab
#: is closed. The default of previous will switch to the last used
#: tab. A value of left will switch to the tab to the left of the
#: closed tab. A value of right will switch to the tab to the right of
#: the closed tab. A value of last will switch to the right-most tab.
# tab_fade 0.25 0.5 0.75 1
#: Control how each tab fades into the background when using fade for
#: the tab_bar_style. Each number is an alpha (between zero and one)
#: that controls how much the corresponding cell fades into the
#: background, with zero being no fade and one being full fade. You
#: can change the number of cells used by adding/removing entries to
#: this list.
# tab_separator " ┇"
#: The separator between tabs in the tab bar when using separator as
#: the tab_bar_style.
# tab_powerline_style slanted
#: The powerline separator style between tabs in the tab bar when
#: using powerline as the tab_bar_style, can be one of: angled,
#: slanted, or round.
# tab_activity_symbol none
#: Some text or a unicode symbol to show on the tab if a window in the
#: tab that does not have focus has some activity. If you want to use
#: leading or trailing spaces surround the text with quotes. See
#: tab_title_template for how this is rendered.
# tab_title_template "{fmt.fg.red}{bell_symbol}{activity_symbol}{fmt.fg.default}{title}"
#: A template to render the tab title. The default just renders the
#: title with optional symbols for bell and activity. If you wish to
#: include the tab-index as well, use something like: {index}:
#: {title}. Useful if you have shortcuts mapped for goto_tab N. If you
#: prefer to see the index as a superscript, use {sup.index}. In
#: addition you can use {layout_name} for the current layout name,
#: {num_windows} for the number of windows in the tab and
#: {num_window_groups} for the number of window groups (not counting
#: overlay windows) in the tab. Note that formatting is done by
#: Python's string formatting machinery, so you can use, for instance,
#: {layout_name[:2].upper()} to show only the first two letters of the
#: layout name, upper-cased. If you want to style the text, you can
#: use styling directives, for example:
#: {fmt.fg.red}red{fmt.fg.default}normal{fmt.bg._00FF00}green
#: bg{fmt.bg.tab}. Similarly, for bold and italic:
#: {fmt.bold}bold{fmt.nobold}normal{fmt.italic}italic{fmt.noitalic}.
#: Note that for backward compatibility, if {bell_symbol} or
#: {activity_symbol} are not present in the template, they are
#: prepended to it.
# active_tab_title_template none
#: Template to use for active tabs, if not specified falls back to
#: tab_title_template.

#: }}}
#: Color scheme {{{
# foreground #dddddd
# background #000000
#: The foreground and background colors
background_opacity 0.75
#: The opacity of the background. A number between 0 and 1, where 1 is
#: opaque and 0 is fully transparent. This will only work if
#: supported by the OS (for instance, when using a compositor under
#: X11). Note that it only sets the background color's opacity in
#: cells that have the same background color as the default terminal
#: background. This is so that things like the status bar in vim,
#: powerline prompts, etc. still look good. But it means that if you
#: use a color theme with a background color in your editor, it will
#: not be rendered as transparent. Instead you should change the
#: default background color in your kitty config and not use a
#: background color in the editor color scheme. Or use the escape
#: codes to set the terminals default colors in a shell script to
#: launch your editor. Be aware that using a value less than 1.0 is a
#: (possibly significant) performance hit. If you want to dynamically
#: change transparency of windows set dynamic_background_opacity to
#: yes (this is off by default as it has a performance cost). Changing
#: this setting when reloading the config will only work if
#: dynamic_background_opacity was enabled in the original config.
# background_image none
#: Path to a background image. Must be in PNG format.
# background_image_layout tiled
#: Whether to tile, scale or clamp the background image. The value can
#: be one of tiled, mirror-tiled, scaled, clamped.
# background_image_linear no
#: When background image is scaled, whether linear interpolation
#: should be used.
# dynamic_background_opacity no
#: Allow changing of the background_opacity dynamically, using either
#: keyboard shortcuts (increase_background_opacity and
#: decrease_background_opacity) or the remote control facility.
#: Changing this setting by reloading the config is not supported.
# background_tint 0.0
#: How much to tint the background image by the background color. The
#: tint is applied only under the text area, not margin/borders. Makes
#: it easier to read the text. Tinting is done using the current
#: background color for each window. This setting applies only if
#: background_opacity is set and transparent windows are supported or
#: background_image is set.
# dim_opacity 0.75
#: How much to dim text that has the DIM/FAINT attribute set. One
#: means no dimming and zero means fully dimmed (i.e. invisible).
# selection_foreground #000000
selection_background #ff7700
#: The foreground and background colors for text selected with the
#: mouse. Setting both of these to none will cause a "reverse video"
#: effect for selections, where the selection will be the cell text
#: color and the text will become the cell background color. Setting
#: only selection_foreground to none will cause the foreground color
#: to be used unchanged. Note that these colors can be overridden by
#: the program running in the terminal.
#: The color table {{{
#: The 256 terminal colors. There are 8 basic colors, each color has a

#: }}}
#: Advanced {{{
# shell .
#: The shell program to execute. The default value of . means to use
#: whatever shell is set as the default shell for the current user.
#: Note that on macOS if you change this, you might need to add
#: --login and --interactive to ensure that the shell starts in
#: interactive mode and reads its startup rc files.
# editor .
#: The terminal editor (such as ``vim`` or ``nano``) to use when
#: editing the kitty config file or similar tasks.
#: The default value of . means to use the environment variables
#: VISUAL and EDITOR in that order. If these variables aren't set,
#: kitty will run your shell (``$SHELL -l -i -c env``) to see if your
#: shell config files set VISUAL or EDITOR. If that doesn't work,
#: kitty will cycle through various known editors (``vim``, ``emacs``,
#: etc) and take the first one that exists on your system.
# close_on_child_death no
#: Close the window when the child process (shell) exits. If no (the
#: default), the terminal will remain open when the child exits as
#: long as there are still processes outputting to the terminal (for
#: example disowned or backgrounded processes). If yes, the window
#: will close as soon as the child process exits. Note that setting it
#: to yes means that any background processes still using the terminal
#: can fail silently because their stdout/stderr/stdin no longer work.
# allow_remote_control no
#: Allow other programs to control kitty. If you turn this on other
#: programs can control all aspects of kitty, including sending text
#: to kitty windows, opening new windows, closing windows, reading the
#: content of windows, etc. Note that this even works over ssh
#: connections. You can chose to either allow any program running
#: within kitty to control it, with yes or only programs that connect
#: to the socket specified with the kitty --listen-on command line
#: option, if you use the value socket-only. The latter is useful if
#: you want to prevent programs running on a remote computer over ssh
#: from controlling kitty. Reloading the config will not affect this
#: setting.
# listen_on none
#: Tell kitty to listen to the specified unix/tcp socket for remote
#: control connections. Note that this will apply to all kitty
#: instances. It can be overridden by the kitty --listen-on command
#: line flag. This option accepts only UNIX sockets, such as
#: unix:${TEMP}/mykitty or (on Linux) unix:@mykitty. Environment
#: variables are expanded. If {kitty_pid} is present then it is
#: replaced by the PID of the kitty process, otherwise the PID of the
#: kitty process is appended to the value, with a hyphen. This option
#: is ignored unless you also set allow_remote_control to enable
#: remote control. See the help for kitty --listen-on for more
#: details. Changing this option by reloading the config is not
#: supported.
# env
#: Specify environment variables to set in all child processes. Note
#: that environment variables are expanded recursively, so if you
#: use::
#: env MYVAR1=a
#: env MYVAR2=${MYVAR1}/${HOME}/b
#: The value of MYVAR2 will be a//b. Using
#: VAR= will set it to the empty string and using just VAR will delete
#: the variable from the child process' environment.
# watcher
#: Path to python file which will be loaded for
#: https://sw.kovidgoyal.net/kitty/launch/#watchers. Can be specified
#: more than once to load multiple watchers. The watchers will be
#: added to every kitty window. Relative paths are resolved relative
#: to the kitty config directory. Note that reloading the config will
#: only affect windows created after the reload.
# exe_search_path
#: Control where kitty looks to find programs to run. The default
#: search order is: First search the system wide PATH, then
#: ~/.local/bin and ~/bin. If not still not found, the PATH defined in
#: the login shell after sourcing all its startup files is tried.
#: Finally, if present, the PATH in the env option is tried.
#: This option allows you to prepend, append, or remove paths from
#: this search order. It can be specified multiple times for multiple
#: paths. A simple path will be prepended to the search order. A path
#: that starts with the + sign will be append to the search order,
#: after ~/bin above. A path that starts with the - sign will be
#: removed from the entire search order. For example::
#: exe_search_path /some/prepended/path
#: exe_search_path +/some/appended/path
#: exe_search_path -/some/excluded/path
# update_check_interval 24
#: Periodically check if an update to kitty is available. If an update
#: is found a system notification is displayed informing you of the
#: available update. The default is to check every 24 hrs, set to zero
#: to disable. Changing this option by reloading the config is not
#: supported.
# startup_session none
#: Path to a session file to use for all kitty instances. Can be
#: overridden by using the kitty --session command line option for
#: individual instances. See
#: https://sw.kovidgoyal.net/kitty/overview/#startup-sessions in the
#: kitty documentation for details. Note that relative paths are
#: interpreted with respect to the kitty config directory. Environment
#: variables in the path are expanded. Changing this option by
#: reloading the config is not supported.
# clipboard_control write-clipboard write-primary read-clipboard-ask read-primary-ask
#: Allow programs running in kitty to read and write from the
#: clipboard. You can control exactly which actions are allowed. The
#: set of possible actions is: write-clipboard read-clipboard write-
#: primary read-primary read-clipboard-ask read-primary-ask. The
#: default is to allow writing to the clipboard and primary selection
#: and to ask for permission when a program tries to read from the
#: clipboard. Note that disabling the read confirmation is a security
#: risk as it means that any program, even one running on a remote
#: server via SSH can read your clipboard. See also
#: clipboard_max_size.
# clipboard_max_size 64
#: The maximum size (in MB) of data from programs running in kitty
#: that will be stored for writing to the system clipboard. See also
#: clipboard_control. A value of zero means no size limit is applied.
# file_transfer_confirmation_bypass
#: A password, that can be supplied to the file transfer kitten to
#: skip the transfer confirmation prompt. This should only be used
#: when initiating transfers from trusted computers, over trusted
#: networks or encrypted transports, as it allows programs running on
#: the remote machine to read/write to the local filesystem, without
#: permission.
# allow_hyperlinks yes
#: Process hyperlink (OSC 8) escape sequences. If disabled OSC 8
#: escape sequences are ignored. Otherwise they become clickable
#: links, that you can click by with the mouse or the hints kitten
#: . The special value of ``ask`` means that kitty
#: will ask before opening the link when clicked.
# shell_integration enabled
#: Enable shell integration on supported shells. This enables features
#: such as jumping to previous prompts, browsing the output of the
#: previous command in a pager, etc. on supported shells. Set to
#: ``disabled`` to turn off shell integration, completely. See
#: https://sw.kovidgoyal.net/kitty/shell-integration/ for details.
# term xterm-kitty
#: The value of the TERM environment variable to set. Changing this
#: can break many terminal programs, only change it if you know what
#: you are doing, not because you read some advice on Stack Overflow
#: to change it. The TERM variable is used by various programs to get
#: information about the capabilities and behavior of the terminal. If
#: you change it, depending on what programs you run, and how
#: different the terminal you are changing it to is, various things
#: from key-presses, to colors, to various advanced features may not
#: work. Changing this option by reloading the config will only affect
#: newly created windows.
#: }}}
#: OS specific tweaks {{{
# wayland_titlebar_color system
#: Change the color of the kitty window's titlebar on Wayland systems
#: with client side window decorations such as GNOME. A value of
#: system means to use the default system color, a value of background
#: means to use the background color of the currently active window
#: and finally you can use an arbitrary color, such as #12af59 or red.
# macos_titlebar_color system
#: Change the color of the kitty window's titlebar on macOS. A value
#: of system means to use the default system color, light or dark can
#: also be used to set it explicitly. A value of background means to
#: use the background color of the currently active window and finally
#: you can use an arbitrary color, such as #12af59 or red. WARNING:
#: This option works by using a hack, as there is no proper Cocoa API
#: for it. It sets the background color of the entire window and makes
#: the titlebar transparent. As such it is incompatible with
#: background_opacity. If you want to use both, you are probably
#: better off just hiding the titlebar with hide_window_decorations.
# macos_option_as_alt no
#: Use the option key as an alt key. With this set to no, kitty will
#: use the macOS native Option+Key = unicode character behavior. This
#: will break any Alt+key keyboard shortcuts in your terminal
#: programs, but you can use the macOS unicode input technique. You
#: can use the values: left, right, or both to use only the left,
#: right or both Option keys as Alt, instead. Changing this setting by
#: reloading the config is not supported.
# macos_hide_from_tasks no
#: Hide the kitty window from running tasks (⌘+Tab) on macOS. Changing
#: this setting by reloading the config is not supported.
# macos_quit_when_last_window_closed no
#: Have kitty quit when all the top-level windows are closed. By
#: default, kitty will stay running, even with no open windows, as is
#: the expected behavior on macOS.
# macos_window_resizable yes
#: Disable this if you want kitty top-level (OS) windows to not be
#: resizable on macOS. Changing this setting by reloading the config
#: will only affect newly created windows.
# macos_thicken_font 0
#: Draw an extra border around the font with the given width, to
#: increase legibility at small font sizes. For example, a value of
#: 0.75 will result in rendering that looks similar to sub-pixel
#: antialiasing at common font sizes.
# macos_traditional_fullscreen no
#: Use the traditional full-screen transition, that is faster, but
#: less pretty.
# macos_show_window_title_in all
#: Show or hide the window title in the macOS window or menu-bar. A
#: value of window will show the title of the currently active window
#: at the top of the macOS window. A value of menubar will show the
#: title of the currently active window in the macOS menu-bar, making
#: use of otherwise wasted space. all will show the title everywhere
#: and none hides the title in the window and the menu-bar.
# macos_custom_beam_cursor no
#: Enable/disable custom mouse cursor for macOS that is easier to see
#: on both light and dark backgrounds. WARNING: this might make your
#: mouse cursor invisible on dual GPU machines. Changing this setting
#: by reloading the config is not supported.
# linux_display_server auto
#: Choose between Wayland and X11 backends. By default, an appropriate
#: backend based on the system state is chosen automatically. Set it
#: to x11 or wayland to force the choice. Changing this setting by
#: reloading the config is not supported.
#: }}}
#: Keyboard shortcuts {{{
#: Keys are identified simply by their lowercase unicode characters.
#: For example: ``a`` for the A key, ``[`` for the left square bracket
#: key, etc. For functional keys, such as ``Enter or Escape`` the
#: names are present at https://sw.kovidgoyal.net/kitty/keyboard-
#: protocol/#functional-key-definitions. For modifier keys, the names
#: are ctrl (control, ⌃), shift (⇧), alt (opt, option, ⌥), super (cmd,
#: command, ⌘). See also: GLFW mods
#:
#: On Linux you can also use XKB key names to bind keys that are not
#: supported by GLFW. See XKB keys
#: for a list of key names. The name to use is the part
#: after the XKB_KEY_ prefix. Note that you can only use an XKB key
#: name for keys that are not known as GLFW keys.
#: Finally, you can use raw system key codes to map keys, again only
#: for keys that are not known as GLFW keys. To see the system key
#: code for a key, start kitty with the kitty --debug-input option.
#: Then kitty will output some debug text for every key event. In that
#: text look for ``native_code`` the value of that becomes the key
#: name in the shortcut. For example:
#: .. code-block:: none
#: on_key_input: glfw key: 65 native_code: 0x61 action: PRESS mods: 0x0 text: 'a'
#: Here, the key name for the A key is 0x61 and you can use it with::
#: map ctrl+0x61 something
#: to map ctrl+a to something.
#: You can use the special action no_op to unmap a keyboard shortcut
#: that is assigned in the default configuration::
#: map kitty_mod+space no_op
#: If you would like kitty to completely ignore a key event, not even
#: sending it to the program running in the terminal, map it to
#: discard_event::
#: map kitty_mod+f1 discard_event
#: You can combine multiple actions to be triggered by a single
#: shortcut, using the syntax below::
#: map key combine action1 action2 action3 ...
#: For example::
#: map kitty_mod+e combine : new_window : next_layout
#: this will create a new window and switch to the next available
#: layout
#: You can use multi-key shortcuts using the syntax shown below::
#: map key1>key2>key3 action
#: For example::
#: map ctrl+f>2 set_font_size 20
#: The full list of actions that can be mapped to key presses is
#: available here .
# kitty_mod ctrl+shift
#: The value of kitty_mod is used as the modifier for all default
#: shortcuts, you can change it in your kitty.conf to change the
#: modifiers for all the default shortcuts.
# clear_all_shortcuts no
#: You can have kitty remove all shortcut definition seen up to this
#: point. Useful, for instance, to remove the default shortcuts.
# action_alias
#: E.g. action_alias launch_tab launch --type=tab --cwd=current
#: Define aliases to avoid repeating the same options in multiple
#: mappings. Aliases can be defined for any action. Aliases are
#: expanded recursively. For example, the above alias allows you to
#: create mappings to launch a new tab in the current working
#: directory without duplication::
#: map f1 launch_tab vim
#: map f2 launch_tab emacs
#: Similarly, to alias kitten invocation::
#: action_alias hints kitten hints --hints-offset=0
# kitten_alias
#: E.g. kitten_alias hints hints --hints-offset=0
#: Like action_alias above but, specifically for kittens. Generally,
#: prefer to use action_alias. This option is a legacy version,
#: present for backwards compatibility. It causes all invocations of
#: the aliased kitten to be substituted. So the example above will
#: cause all invocations of the hints kitten to have the --hints-
#: offset=0 option applied.
#: Clipboard {{{
#: Copy to clipboard
# map kitty_mod+c copy_to_clipboard
#:: There is also a copy_or_interrupt action that can be optionally
#:: mapped to Ctrl+c. It will copy only if there is a selection and
#:: send an interrupt otherwise. Similarly,
#:: copy_and_clear_or_interrupt will copy and clear the selection or
#:: send an interrupt if there is no selection.
#: Paste from clipboard
# map kitty_mod+v paste_from_clipboard
#: Paste from selection
# map kitty_mod+s paste_from_selection
# map shift+insert paste_from_selection

``` # vim:fileencoding=utf-8:foldmethod=marker #: Fonts {{{ #: kitty has very powerful font management. You can configure #: individual font faces and even specify special fonts for particular #: characters. font_family Menlo # bold_font auto # italic_font auto # bold_italic_font auto #: You can specify different fonts for the bold/italic/bold-italic #: variants. To get a full list of supported fonts use the `kitty #: list-fonts` command. By default they are derived automatically, by #: the OSes font system. When bold_font or bold_italic_font is set to #: auto on macOS, the priority of bold fonts is semi-bold, bold, #: heavy. Setting them manually is useful for font families that have #: many weight variants like Book, Medium, Thick, etc. For example:: #: font_family Operator Mono Book #: bold_font Operator Mono Medium #: italic_font Operator Mono Book Italic #: bold_italic_font Operator Mono Medium Italic font_size 14.0 #: Font size (in pts) # force_ltr no #: kitty does not support BIDI (bidirectional text), however, for RTL #: scripts, words are automatically displayed in RTL. That is to say, #: in an RTL script, the words "HELLO WORLD" display in kitty as #: "WORLD HELLO", and if you try to select a substring of an RTL- #: shaped string, you will get the character that would be there had #: the the string been LTR. For example, assuming the Hebrew word #: ירושלים, selecting the character that on the screen appears to be ם #: actually writes into the selection buffer the character י. kitty's #: default behavior is useful in conjunction with a filter to reverse #: the word order, however, if you wish to manipulate RTL glyphs, it #: can be very challenging to work with, so this option is provided to #: turn it off. Furthermore, this option can be used with the command #: line program GNU FriBidi #:. You #: can specify multiple code points, separated by commas and ranges #: separated by hyphens. symbol_map itself can be specified multiple #: times. Syntax is:: #: symbol_map codepoints Font Family Name # disable_ligatures never #: Choose how you want to handle multi-character ligatures. The #: default is to always render them. You can tell kitty to not render #: them when the cursor is over them by using cursor to make editing #: easier, or have kitty never render them at all by using always, if #: you don't like them. The ligature strategy can be set per-window #: either using the kitty remote control facility or by defining #: shortcuts for it in kitty.conf, for example:: #: map alt+1 disable_ligatures_in active always #: map alt+2 disable_ligatures_in all never #: map alt+3 disable_ligatures_in tab cursor #: Note that this refers to programming ligatures, typically #: implemented using the calt OpenType feature. For disabling general #: ligatures, use the font_features setting. # font_features #: E.g. font_features none #: Choose exactly which OpenType features to enable or disable. This #: is useful as some fonts might have features worthwhile in a #: terminal. For example, Fira Code Retina includes a discretionary #: feature, zero, which in that font changes the appearance of the #: zero (0), to make it more easily distinguishable from Ø. Fira Code #: Retina also includes other discretionary features known as #: Stylistic Sets which have the tags ss01 through ss20. #: For the exact syntax to use for individual features, see the #: Harfbuzz documentation.
#: Note that this code is indexed by PostScript name, and not the font
#: family. This allows you to define very precise feature settings;
#: e.g. you can disable a feature in the italic font but not in the
#: regular font.
#: On Linux, these are read from the FontConfig database first and
#: then this, setting is applied, so they can be configured in a
#: single, central place.
#: To get the PostScript name for a font, use kitty + list-fonts
#: --psnames:
#: .. code-block:: sh
#: $ kitty + list-fonts --psnames | grep Fira
#: Fira Code
#: Fira Code Bold (FiraCode-Bold)
#: Fira Code Light (FiraCode-Light)
#: Fira Code Medium (FiraCode-Medium)
#: Fira Code Regular (FiraCode-Regular)
#: Fira Code Retina (FiraCode-Retina)
#: The part in brackets is the PostScript name.
#: Enable alternate zero and oldstyle numerals::
#: font_features FiraCode-Retina +zero +onum
#: Enable only alternate zero::
#: font_features FiraCode-Retina +zero
#: Disable the normal ligatures, but keep the calt feature which (in
#: this font) breaks up monotony::
#: font_features TT2020StyleB-Regular -liga +calt
#: In conjunction with force_ltr, you may want to disable Arabic
#: shaping entirely, and only look at their isolated forms if they
#: show up in a document. You can do this with e.g.::
#: font_features UnifontMedium +isol -medi -fina -init
# box_drawing_scale 0.001, 1, 1.5, 2
#: Change the sizes of the lines used for the box drawing unicode
#: characters These values are in pts. They will be scaled by the
#: monitor DPI to arrive at a pixel value. There must be four values
#: corresponding to thin, normal, thick, and very thick lines.
#: }}}
#: Cursor customization {{{
cursor #81b400
#: Default cursor color. If set to the special value none the cursor
#: will be rendered with a "reverse video" effect. It's color will be
#: the color of the text in the cell it is over and the text will be
#: rendered with the background color of the cell. Note that if the
#: program running in the terminal sets a cursor color, this takes
#: precedence. Also, the cursor colors are modified if the cell
#: background and foreground colors have very low contrast.
# cursor_text_color #111111
#: Choose the color of text under the cursor. If you want it rendered
#: with the background color of the cell underneath instead, use the
#: special keyword: background. Note that if cursor is set to none
#: then this setting is ignored.
cursor_shape block
#: The cursor shape can be one of (block, beam, underline). Note that
#: when reloading the config this will be changed only if the cursor
#: shape has not been set by the program running in the terminal. This
#: sets the default cursor shape. Applications running in the terminal
#: can override it. In particular,
#: https://sw.kovidgoyal.net/kitty/shell-integration/ in kitty sets
#: the cursor shape to beam at shell prompts. You can avoid this by
#: setting shell_integration to no-cursor.
# cursor_beam_thickness 1.5
#: Defines the thickness of the beam cursor (in pts)
# cursor_underline_thickness 2.0
#: Defines the thickness of the underline cursor (in pts)
cursor_blink_interval 0.20
#: The interval (in seconds) at which to blink the cursor. Set to zero
#: to disable blinking. Negative values mean use system default. Note
#: that numbers smaller than repaint_delay will be limited to
#: repaint_delay.
cursor_stop_blinking_after 1.0
#: Stop blinking cursor after the specified number of seconds of
#: keyboard inactivity. Set to zero to never stop blinking.
#: }}}
#: Scrollback {{{
scrollback_lines 2000000
#: Number of lines of history to keep in memory for scrolling back.
#: Memory is allocated on demand. Negative numbers are (effectively)
#: infinite scrollback. Note that using very large scrollback is not
#: recommended as it can slow down performance of the terminal and
#: also use large amounts of RAM. Instead, consider using
#: scrollback_pager_history_size. Note that on config reload if this
#: is changed it will only affect newly created windows, not existing
#: ones.
# scrollback_pager less --chop-long-lines --RAW-CONTROL-CHARS +INPUT_LINE_NUMBER
#: Program with which to view scrollback in a new window. The
#: scrollback buffer is passed as STDIN to this program. If you change
#: it, make sure the program you use can handle ANSI escape sequences
#: for colors and text formatting. INPUT_LINE_NUMBER in the command
#: line above will be replaced by an integer representing which line
#: should be at the top of the screen. Similarly CURSOR_LINE and
#: CURSOR_COLUMN will be replaced by the current cursor position or
#: set to 0 if there is no cursor, for example, when showing the last
#: command output.
# scrollback_pager_history_size 0
#: Separate scrollback history size, used only for browsing the
#: scrollback buffer (in MB). This separate buffer is not available
#: for interactive scrolling but will be piped to the pager program
#: when viewing scrollback buffer in a separate window. The current
#: implementation stores the data in UTF-8, so approximatively 10000
#: lines per megabyte at 100 chars per line, for pure ASCII text,
#: unformatted text. A value of zero or less disables this feature.
#: The maximum allowed size is 4GB. Note that on config reload if this
#: is changed it will only affect newly created windows, not existing
#: ones.
# scrollback_fill_enlarged_window no
#: Fill new space with lines from the scrollback buffer after
#: enlarging a window.
# wheel_scroll_multiplier 5.0
#: Modify the amount scrolled by the mouse wheel. Note this is only
#: used for low precision scrolling devices, not for high precision
#: scrolling on platforms such as macOS and Wayland. Use negative
#: numbers to change scroll direction.
# touch_scroll_multiplier 1.0
#: Modify the amount scrolled by a touchpad. Note this is only used
#: for high precision scrolling devices on platforms such as macOS and
#: Wayland. Use negative numbers to change scroll direction.
#: }}}
#: Mouse {{{
# mouse_hide_wait 3.0
#: Hide mouse cursor after the specified number of seconds of the
#: mouse not being used. Set to zero to disable mouse cursor hiding.
#: Set to a negative value to hide the mouse cursor immediately when
#: typing text. Disabled by default on macOS as getting it to work
#: robustly with the ever-changing sea of bugs that is Cocoa is too
#: much effort.
# url_color #0087bd
url_style double
#: The color and style for highlighting URLs on mouse-over. url_style
#: can be one of: none, straight, double, curly, dotted, dashed
# open_url_with default
#: The program with which to open URLs that are clicked on. The
#: special value default means to use the operating system's default
#: URL handler (open on macOS and xdg-open on Linux).
# url_prefixes http https file ftp gemini irc gopher mailto news git
#: The set of URL prefixes to look for when detecting a URL under the
#: mouse cursor.
# detect_urls yes
#: Detect URLs under the mouse. Detected URLs are highlighted with an
#: underline and the mouse cursor becomes a hand over them. Even if
#: this option is disabled, URLs are still clickable.
# url_excluded_characters
#: Additional characters to be disallowed from URLs, when detecting
#: URLs under the mouse cursor. By default, all characters legal in
#: URLs are allowed.
# copy_on_select no
#: Copy to clipboard or a private buffer on select. With this set to
#: clipboard, simply selecting text with the mouse will cause the text
#: to be copied to clipboard. Useful on platforms such as macOS that
#: do not have the concept of primary selections. You can instead
#: specify a name such as a1 to copy to a private kitty buffer
#: instead. Map a shortcut with the paste_from_buffer action to paste
#: from this private buffer. For example::
#: map shift+cmd+v paste_from_buffer a1
#: Note that copying to the clipboard is a security risk, as all
#: programs, including websites open in your browser can read the
#: contents of the system clipboard.
# strip_trailing_spaces never
#: Remove spaces at the end of lines when copying to clipboard. A
#: value of smart will do it when using normal selections, but not
#: rectangle selections. always will always do it.
# select_by_word_characters @-./_~?&=%+#
#: Characters considered part of a word when double clicking. In
#: addition to these characters any character that is marked as an
#: alphanumeric character in the unicode database will be matched.
# click_interval -1.0
#: The interval between successive clicks to detect double/triple
#: clicks (in seconds). Negative numbers will use the system default
#: instead, if available, or fallback to 0.5.
# focus_follows_mouse no
#: Set the active window to the window under the mouse when moving the
#: mouse around
# pointer_shape_when_grabbed arrow
#: The shape of the mouse pointer when the program running in the
#: terminal grabs the mouse. Valid values are: arrow, beam and hand
# default_pointer_shape beam
#: The default shape of the mouse pointer. Valid values are: arrow,
#: beam and hand
# pointer_shape_when_dragging beam
#: The default shape of the mouse pointer when dragging across text.
#: Valid values are: arrow, beam and hand
#: Mouse actions {{{
#: Mouse buttons can be remapped to perform arbitrary actions. The
#: syntax for doing so is:
#: .. code-block:: none
#: mouse_map button-name event-type modes action
#: Where ``button-name`` is one of ``left``, ``middle``, ``right`` or
#: ``b1 ... b8`` with added keyboard modifiers, for example:
#: ``ctrl+shift+left`` refers to holding the ctrl+shift keys while
#: clicking with the left mouse button. The number ``b1 ... b8`` can
#: be used to refer to upto eight buttons on a mouse.
#: ``event-type`` is one ``press``, ``release``, ``doublepress``,
#: ``triplepress``, ``click`` and ``doubleclick``. ``modes``
#: indicates whether the action is performed when the mouse is grabbed
#: by the program running in the terminal, or not. It can have one or
#: more or the values, ``grabbed,ungrabbed``. ``grabbed`` refers to
#: when the program running in the terminal has requested mouse
#: events. Note that the click and double click events have a delay of
#: click_interval to disambiguate from double and triple presses.
#: You can run kitty with the kitty --debug-input command line option
#: to see mouse events. See the builtin actions below to get a sense
#: of what is possible.
#: If you want to unmap an action map it to ``no-op``. For example, to
#: disable opening of URLs with a plain click::
#: mouse_map left click ungrabbed no-op
#: .. note::
#: Once a selection is started, releasing the button that started it will
#: automatically end it and no release event will be dispatched.
# clear_all_mouse_actions no
#: You can have kitty remove all mouse actions seen up to this point.
#: Useful, for instance, to remove the default mouse actions.
#: Click the link under the mouse or move the cursor
# mouse_map left click ungrabbed mouse_handle_click selection link prompt
#:: First check for a selection and if one exists do nothing. Then

#: Performance tuning {{{
# repaint_delay 10
#: Delay (in milliseconds) between screen updates. Decreasing it,
#: increases frames-per-second (FPS) at the cost of more CPU usage.
#: The default value yields ~100 FPS which is more than sufficient for
#: most uses. Note that to actually achieve 100 FPS you have to either
#: set sync_to_monitor to no or use a monitor with a high refresh
#: rate. Also, to minimize latency when there is pending input to be
#: processed, repaint_delay is ignored.
# input_delay 3
#: Delay (in milliseconds) before input from the program running in
#: the terminal is processed. Note that decreasing it will increase
#: responsiveness, but also increase CPU usage and might cause flicker
#: in full screen programs that redraw the entire screen on each loop,
#: because kitty is so fast that partial screen updates will be drawn.
# sync_to_monitor yes
#: Sync screen updates to the refresh rate of the monitor. This
#: prevents tearing (https://en.wikipedia.org/wiki/Screen_tearing)
#: when scrolling. However, it limits the rendering speed to the
#: refresh rate of your monitor. With a very high speed mouse/high

#: as number of cells instead of pixels.
# enabled_layouts *
#: The enabled window layouts. A comma separated list of layout names.
#: The special value all means all layouts. The first listed layout
#: will be used as the startup layout. Default configuration is all
#: layouts in alphabetical order. For a list of available layouts, see
#: the https://sw.kovidgoyal.net/kitty/overview/#layouts.
# window_resize_step_cells 2
# window_resize_step_lines 2
#: The step size (in units of cell width/cell height) to use when
#: resizing kitty windows in a layout with the keyboard
#: (start_resizing_window). The cells value is used for horizontal
#: resizing and the lines value for vertical resizing.
# window_border_width 0.5pt
#: The width of window borders. Can be either in pixels (px) or pts
#: (pt). Values in pts will be rounded to the nearest number of pixels
#: based on screen resolution. If not specified the unit is assumed to
#: be pts. Note that borders are displayed only when more than one
#: window is visible. They are meant to separate multiple windows.
# draw_minimal_borders yes
#: Draw only the minimum borders needed. This means that only the
#: minimum needed borders for inactive windows are drawn. That is only
#: the borders that separate the inactive window from a neighbor. Note
#: that setting a non-zero window margin overrides this and causes all
#: borders to be drawn.
# window_margin_width 0
#: The window margin (in pts) (blank area outside the border). A
#: single value sets all four sides. Two values set the vertical and
#: horizontal sides. Three values set top, horizontal and bottom. Four
#: values set top, right, bottom and left.
# single_window_margin_width -1
#: The window margin (in pts) to use when only a single window is
#: visible. Negative values will cause the value of
#: window_margin_width to be used instead. A single value sets all
#: four sides. Two values set the vertical and horizontal sides. Three
#: values set top, horizontal and bottom. Four values set top, right,
#: bottom and left.
# window_padding_width 0
#: The window padding (in pts) (blank area between the text and the
#: window border). A single value sets all four sides. Two values set
#: the vertical and horizontal sides. Three values set top, horizontal
#: and bottom. Four values set top, right, bottom and left.
# placement_strategy center
#: When the window size is not an exact multiple of the cell size, the
#: cell area of the terminal window will have some extra padding on
#: the sides. You can control how that padding is distributed with
#: this option. Using a value of center means the cell area will be
#: placed centrally. A value of top-left means the padding will be on
#: only the bottom and right edges.
# active_border_color #00ff00
#: The color for the border of the active window. Set this to none to
#: not draw borders around the active window.
# inactive_border_color #cccccc
#: The color for the border of inactive windows
# bell_border_color #ff5a00
#: The color for the border of inactive windows in which a bell has
#: occurred
# inactive_text_alpha 1.0
#: Fade the text in inactive windows by the specified amount (a number
#: between zero and one, with zero being fully faded).
# hide_window_decorations no
#: Hide the window decorations (title-bar and window borders) with
#: yes. On macOS, titlebar-only can be used to only hide the titlebar.
#: Whether this works and exactly what effect it has depends on the
#: window manager/operating system. Note that the effects of changing
#: this setting when reloading config are undefined.
# window_logo_path none
#: Path to a logo image. Must be in PNG format. Relative paths are
#: interpreted relative to the kitty config directory. The logo is
#: displayed in a corner of every kitty window. The position is
#: controlled by window_logo_position. Individual windows can be
#: configured to have different logos either using the launch function
#: or the remote-control facility.
# window_logo_position bottom-right
#: Where to position the window logo in the window. The value can be
#: one of: top-left, top, top-right, left, center, right, bottom-left,
#: bottom, bottom-right.
# window_logo_alpha 0.5
#: The amount the logo should be faded into the background. With zero
#: being fully faded and one being fully opaque.
# resize_debounce_time 0.1
#: The time (in seconds) to wait before redrawing the screen when a
#: resize event is received. On platforms such as macOS, where the
#: operating system sends events corresponding to the start and end of
#: a resize, this number is ignored.
# resize_draw_strategy static
#: Choose how kitty draws a window while a resize is in progress. A
#: value of static means draw the current window contents, mostly
#: unchanged. A value of scale means draw the current window contents
#: scaled. A value of blank means draw a blank window. A value of size
#: means show the window size in cells.
# resize_in_steps no
#: Resize the OS window in steps as large as the cells, instead of
#: with the usual pixel accuracy. Combined with an
#: initial_window_width and initial_window_height in number of cells,
#: this option can be used to keep the margins as small as possible
#: when resizing the OS window. Note that this does not currently work
#: on Wayland.
# visual_window_select_characters 1234567890ABCDEFGHIJKLMNOPQRSTUVWXYZ
#: The list of characters to use for visual window selection (for
#: example for selecting a window to focus with focus_visible_window).
#: The value should be a series of unique numbers or alphabets, case
#: insensitive, from the set [0-9A-Z]. Specify your preference as a
#: string of characters.
# confirm_os_window_close 0
#: Ask for confirmation when closing an OS window or a Tab with at
#: least this number of kitty windows in it by window manager (e.g.
#: clicking the window close button or pressing the Operating system
#: shortcut to close windows) or by the close_tab action. A value of
#: zero disables confirmation. This confirmation also applies to
#: requests to quit the entire application (all OS windows, via the
#: quit action). Negative values are converted to positive ones,
#: however, with https://sw.kovidgoyal.net/kitty/shell-integration/
#: enabled, using negative values means windows sitting at a shell
#: prompt are not counted, only windows where some command is
#: currently running. Note that if you want confirmation when closing
#: individual windows, you can map the
#: https://sw.kovidgoyal.net/kitty/actions/#close-window-with-
#: confirmation action.
#: }}}
#: Tab bar {{{
tab_bar_edge top
#: Which edge to show the tab bar on, top or bottom
# tab_bar_margin_width 0.0
#: The margin to the left and right of the tab bar (in pts)
# tab_bar_margin_height 0.0 0.0
#: The margin above and below the tab bar (in pts). The first number
#: is the margin between the edge of the OS Window and the tab bar and
#: the second number is the margin between the tab bar and the
#: contents of the current tab.
tab_bar_style slant
#: The tab bar style, can be one of:
#: fade
#: Each tab's edges fade into the background color (see tab_fade)
#: slant
#: Tabs look like the tabs in a physical file
#: separator
#: Tabs are separated by a configurable separator (see tab_separator)
#: powerline
#: Tabs are shown as a continuous line with "fancy" separators
#: (see tab_powerline_style)
#: custom
#: A user-supplied Python function called draw_tab is loaded from the file
#: tab_bar.py in the kitty config directory. For examples of how to
#: write such a function, see the functions named draw_tab_with_* in
#: kitty's source code: kitty/tab_bar.py. See also
#: this discussion <4447> for examples from kitty users.
#: hidden
#: The tab bar is hidden. If you use this, you might want to create a
#: mapping for the https://sw.kovidgoyal.net/kitty/actions/#select-tab
#: action which presents you with a list of tabs and allows for easy
#: switching to a tab.
tab_bar_align center
#: The horizontal alignment of the tab bar, can be one of: left,
#: center, or right.
tab_bar_min_tabs 1
#: The minimum number of tabs that must exist before the tab bar is
#: shown
# tab_switch_strategy previous
#: The algorithm to use when switching to a tab when the current tab
#: is closed. The default of previous will switch to the last used
#: tab. A value of left will switch to the tab to the left of the
#: closed tab. A value of right will switch to the tab to the right of
#: the closed tab. A value of last will switch to the right-most tab.
# tab_fade 0.25 0.5 0.75 1
#: Control how each tab fades into the background when using fade for
#: the tab_bar_style. Each number is an alpha (between zero and one)
#: that controls how much the corresponding cell fades into the
#: background, with zero being no fade and one being full fade. You
#: can change the number of cells used by adding/removing entries to
#: this list.
# tab_separator " ┇"
#: The separator between tabs in the tab bar when using separator as
#: the tab_bar_style.
# tab_powerline_style slanted
#: The powerline separator style between tabs in the tab bar when
#: using powerline as the tab_bar_style, can be one of: angled,
#: slanted, or round.
# tab_activity_symbol none
#: Some text or a unicode symbol to show on the tab if a window in the
#: tab that does not have focus has some activity. If you want to use
#: leading or trailing spaces surround the text with quotes. See
#: tab_title_template for how this is rendered.
# tab_title_template "{fmt.fg.red}{bell_symbol}{activity_symbol}{fmt.fg.default}{title}"
#: A template to render the tab title. The default just renders the
#: title with optional symbols for bell and activity. If you wish to
#: include the tab-index as well, use something like: {index}:
#: {title}. Useful if you have shortcuts mapped for goto_tab N. If you
#: prefer to see the index as a superscript, use {sup.index}. In
#: addition you can use {layout_name} for the current layout name,
#: {num_windows} for the number of windows in the tab and
#: {num_window_groups} for the number of window groups (not counting
#: overlay windows) in the tab. Note that formatting is done by
#: Python's string formatting machinery, so you can use, for instance,
#: {layout_name[:2].upper()} to show only the first two letters of the
#: layout name, upper-cased. If you want to style the text, you can
#: use styling directives, for example:
#: {fmt.fg.red}red{fmt.fg.default}normal{fmt.bg._00FF00}green
#: bg{fmt.bg.tab}. Similarly, for bold and italic:
#: {fmt.bold}bold{fmt.nobold}normal{fmt.italic}italic{fmt.noitalic}.
#: Note that for backward compatibility, if {bell_symbol} or
#: {activity_symbol} are not present in the template, they are
#: prepended to it.
# active_tab_title_template none
#: Template to use for active tabs, if not specified falls back to
#: tab_title_template.

#: background color.
#: }}}
#: Color scheme {{{
# foreground #dddddd
# background #000000
#: The foreground and background colors
background_opacity 0.75
#: The opacity of the background. A number between 0 and 1, where 1 is
#: opaque and 0 is fully transparent. This will only work if
#: supported by the OS (for instance, when using a compositor under
#: X11). Note that it only sets the background color's opacity in
#: cells that have the same background color as the default terminal
#: background. This is so that things like the status bar in vim,
#: powerline prompts, etc. still look good. But it means that if you
#: use a color theme with a background color in your editor, it will
#: not be rendered as transparent. Instead you should change the
#: default background color in your kitty config and not use a
#: background color in the editor color scheme. Or use the escape
#: codes to set the terminals default colors in a shell script to
#: launch your editor. Be aware that using a value less than 1.0 is a
#: (possibly significant) performance hit. If you want to dynamically
#: change transparency of windows set dynamic_background_opacity to
#: yes (this is off by default as it has a performance cost). Changing
#: this setting when reloading the config will only work if
#: dynamic_background_opacity was enabled in the original config.
# background_image none
#: Path to a background image. Must be in PNG format.
# background_image_layout tiled
#: Whether to tile, scale or clamp the background image. The value can
#: be one of tiled, mirror-tiled, scaled, clamped.
# background_image_linear no
#: When background image is scaled, whether linear interpolation
#: should be used.
# dynamic_background_opacity no
#: Allow changing of the background_opacity dynamically, using either
#: keyboard shortcuts (increase_background_opacity and
#: decrease_background_opacity) or the remote control facility.
#: Changing this setting by reloading the config is not supported.
# background_tint 0.0
#: How much to tint the background image by the background color. The
#: tint is applied only under the text area, not margin/borders. Makes
#: it easier to read the text. Tinting is done using the current
#: background color for each window. This setting applies only if
#: background_opacity is set and transparent windows are supported or
#: background_image is set.
# dim_opacity 0.75
#: How much to dim text that has the DIM/FAINT attribute set. One
#: means no dimming and zero means fully dimmed (i.e. invisible).
# selection_foreground #000000
selection_background #ff7700
#: The foreground and background colors for text selected with the
#: mouse. Setting both of these to none will cause a "reverse video"
#: effect for selections, where the selection will be the cell text
#: color and the text will become the cell background color. Setting
#: only selection_foreground to none will cause the foreground color
#: to be used unchanged. Note that these colors can be overridden by
#: the program running in the terminal.
#: The color table {{{
#: The 256 terminal colors. There are 8 basic colors, each color has a

#: Advanced {{{
# shell .
#: The shell program to execute. The default value of . means to use
#: whatever shell is set as the default shell for the current user.
#: Note that on macOS if you change this, you might need to add
#: --login and --interactive to ensure that the shell starts in
#: interactive mode and reads its startup rc files.
# editor .
#: The terminal editor (such as ``vim`` or ``nano``) to use when
#: editing the kitty config file or similar tasks.
#: The default value of . means to use the environment variables
#: VISUAL and EDITOR in that order. If these variables aren't set,
#: kitty will run your shell (``$SHELL -l -i -c env``) to see if your
#: shell config files set VISUAL or EDITOR. If that doesn't work,
#: kitty will cycle through various known editors (``vim``, ``emacs``,
#: etc) and take the first one that exists on your system.
# close_on_child_death no
#: Close the window when the child process (shell) exits. If no (the
#: default), the terminal will remain open when the child exits as
#: long as there are still processes outputting to the terminal (for
#: example disowned or backgrounded processes). If yes, the window
#: will close as soon as the child process exits. Note that setting it
#: to yes means that any background processes still using the terminal
#: can fail silently because their stdout/stderr/stdin no longer work.
# allow_remote_control no
#: Allow other programs to control kitty. If you turn this on other
#: programs can control all aspects of kitty, including sending text
#: to kitty windows, opening new windows, closing windows, reading the
#: content of windows, etc. Note that this even works over ssh
#: connections. You can chose to either allow any program running
#: within kitty to control it, with yes or only programs that connect
#: to the socket specified with the kitty --listen-on command line
#: option, if you use the value socket-only. The latter is useful if
#: you want to prevent programs running on a remote computer over ssh
#: from controlling kitty. Reloading the config will not affect this
#: setting.
# listen_on none
#: Tell kitty to listen to the specified unix/tcp socket for remote
#: control connections. Note that this will apply to all kitty
#: instances. It can be overridden by the kitty --listen-on command
#: line flag. This option accepts only UNIX sockets, such as
#: unix:${TEMP}/mykitty or (on Linux) unix:@mykitty. Environment
#: variables are expanded. If {kitty_pid} is present then it is
#: replaced by the PID of the kitty process, otherwise the PID of the
#: kitty process is appended to the value, with a hyphen. This option
#: is ignored unless you also set allow_remote_control to enable
#: remote control. See the help for kitty --listen-on for more
#: details. Changing this option by reloading the config is not
#: supported.
# env
#: Specify environment variables to set in all child processes. Note
#: that environment variables are expanded recursively, so if you
#: use::
#: env MYVAR1=a
#: env MYVAR2=${MYVAR1}/${HOME}/b
#: The value of MYVAR2 will be a//b. Using
#: VAR= will set it to the empty string and using just VAR will delete
#: the variable from the child process' environment.
# watcher
#: Path to python file which will be loaded for
#: https://sw.kovidgoyal.net/kitty/launch/#watchers. Can be specified
#: more than once to load multiple watchers. The watchers will be
#: added to every kitty window. Relative paths are resolved relative
#: to the kitty config directory. Note that reloading the config will
#: only affect windows created after the reload.
# exe_search_path
#: Control where kitty looks to find programs to run. The default
#: search order is: First search the system wide PATH, then
#: ~/.local/bin and ~/bin. If not still not found, the PATH defined in
#: the login shell after sourcing all its startup files is tried.
#: Finally, if present, the PATH in the env option is tried.
#: This option allows you to prepend, append, or remove paths from
#: this search order. It can be specified multiple times for multiple
#: paths. A simple path will be prepended to the search order. A path
#: that starts with the + sign will be append to the search order,
#: after ~/bin above. A path that starts with the - sign will be
#: removed from the entire search order. For example::
#: exe_search_path /some/prepended/path
#: exe_search_path +/some/appended/path
#: exe_search_path -/some/excluded/path
# update_check_interval 24
#: Periodically check if an update to kitty is available. If an update
#: is found a system notification is displayed informing you of the
#: available update. The default is to check every 24 hrs, set to zero
#: to disable. Changing this option by reloading the config is not
#: supported.
# startup_session none
#: Path to a session file to use for all kitty instances. Can be
#: overridden by using the kitty --session command line option for
#: individual instances. See
#: https://sw.kovidgoyal.net/kitty/overview/#startup-sessions in the
#: kitty documentation for details. Note that relative paths are
#: interpreted with respect to the kitty config directory. Environment
#: variables in the path are expanded. Changing this option by
#: reloading the config is not supported.
# clipboard_control write-clipboard write-primary read-clipboard-ask read-primary-ask
#: Allow programs running in kitty to read and write from the
#: clipboard. You can control exactly which actions are allowed. The
#: set of possible actions is: write-clipboard read-clipboard write-
#: primary read-primary read-clipboard-ask read-primary-ask. The
#: default is to allow writing to the clipboard and primary selection
#: and to ask for permission when a program tries to read from the
#: clipboard. Note that disabling the read confirmation is a security
#: risk as it means that any program, even one running on a remote
#: server via SSH can read your clipboard. See also
#: clipboard_max_size.
# clipboard_max_size 64
#: The maximum size (in MB) of data from programs running in kitty
#: that will be stored for writing to the system clipboard. See also
#: clipboard_control. A value of zero means no size limit is applied.
# file_transfer_confirmation_bypass
#: A password, that can be supplied to the file transfer kitten to
#: skip the transfer confirmation prompt. This should only be used
#: when initiating transfers from trusted computers, over trusted
#: networks or encrypted transports, as it allows programs running on
#: the remote machine to read/write to the local filesystem, without
#: permission.
# allow_hyperlinks yes
#: Process hyperlink (OSC 8) escape sequences. If disabled OSC 8
#: escape sequences are ignored. Otherwise they become clickable
#: links, that you can click by with the mouse or the hints kitten
#: . The special value of ``ask`` means that kitty
#: will ask before opening the link when clicked.
# shell_integration enabled
#: Enable shell integration on supported shells. This enables features
#: such as jumping to previous prompts, browsing the output of the
#: previous command in a pager, etc. on supported shells. Set to
#: ``disabled`` to turn off shell integration, completely. See
#: https://sw.kovidgoyal.net/kitty/shell-integration/ for details.
# term xterm-kitty
#: The value of the TERM environment variable to set. Changing this
#: can break many terminal programs, only change it if you know what
#: you are doing, not because you read some advice on Stack Overflow
#: to change it. The TERM variable is used by various programs to get
#: information about the capabilities and behavior of the terminal. If
#: you change it, depending on what programs you run, and how
#: different the terminal you are changing it to is, various things
#: from key-presses, to colors, to various advanced features may not
#: work. Changing this option by reloading the config will only affect
#: newly created windows.
#: }}}
#: OS specific tweaks {{{
# wayland_titlebar_color system
#: Change the color of the kitty window's titlebar on Wayland systems
#: with client side window decorations such as GNOME. A value of
#: system means to use the default system color, a value of background
#: means to use the background color of the currently active window
#: and finally you can use an arbitrary color, such as #12af59 or red.
# macos_titlebar_color system
#: Change the color of the kitty window's titlebar on macOS. A value
#: of system means to use the default system color, light or dark can
#: also be used to set it explicitly. A value of background means to
#: use the background color of the currently active window and finally
#: you can use an arbitrary color, such as #12af59 or red. WARNING:
#: This option works by using a hack, as there is no proper Cocoa API
#: for it. It sets the background color of the entire window and makes
#: the titlebar transparent. As such it is incompatible with
#: background_opacity. If you want to use both, you are probably
#: better off just hiding the titlebar with hide_window_decorations.
# macos_option_as_alt no
#: Use the option key as an alt key. With this set to no, kitty will
#: use the macOS native Option+Key = unicode character behavior. This
#: will break any Alt+key keyboard shortcuts in your terminal
#: programs, but you can use the macOS unicode input technique. You
#: can use the values: left, right, or both to use only the left,
#: right or both Option keys as Alt, instead. Changing this setting by
#: reloading the config is not supported.
# macos_hide_from_tasks no
#: Hide the kitty window from running tasks (⌘+Tab) on macOS. Changing
#: this setting by reloading the config is not supported.
# macos_quit_when_last_window_closed no
#: Have kitty quit when all the top-level windows are closed. By
#: default, kitty will stay running, even with no open windows, as is
#: the expected behavior on macOS.
# macos_window_resizable yes
#: Disable this if you want kitty top-level (OS) windows to not be
#: resizable on macOS. Changing this setting by reloading the config
#: will only affect newly created windows.
# macos_thicken_font 0
#: Draw an extra border around the font with the given width, to
#: increase legibility at small font sizes. For example, a value of
#: 0.75 will result in rendering that looks similar to sub-pixel
#: antialiasing at common font sizes.
# macos_traditional_fullscreen no
#: Use the traditional full-screen transition, that is faster, but
#: less pretty.
# macos_show_window_title_in all
#: Show or hide the window title in the macOS window or menu-bar. A
#: value of window will show the title of the currently active window
#: at the top of the macOS window. A value of menubar will show the
#: title of the currently active window in the macOS menu-bar, making
#: use of otherwise wasted space. all will show the title everywhere
#: and none hides the title in the window and the menu-bar.
# macos_custom_beam_cursor no
#: Enable/disable custom mouse cursor for macOS that is easier to see
#: on both light and dark backgrounds. WARNING: this might make your
#: mouse cursor invisible on dual GPU machines. Changing this setting
#: by reloading the config is not supported.
# linux_display_server auto
#: Choose between Wayland and X11 backends. By default, an appropriate
#: backend based on the system state is chosen automatically. Set it
#: to x11 or wayland to force the choice. Changing this setting by
#: reloading the config is not supported.
#: }}}
#: Keyboard shortcuts {{{
#: Keys are identified simply by their lowercase unicode characters.
#: For example: ``a`` for the A key, ``[`` for the left square bracket
#: key, etc. For functional keys, such as ``Enter or Escape`` the
#: names are present at https://sw.kovidgoyal.net/kitty/keyboard-
#: protocol/#functional-key-definitions. For modifier keys, the names
#: are ctrl (control, ⌃), shift (⇧), alt (opt, option, ⌥), super (cmd,
#: command, ⌘). See also: GLFW mods
#:
#: On Linux you can also use XKB key names to bind keys that are not
#: supported by GLFW. See XKB keys
#: for a list of key names. The name to use is the part
#: after the XKB_KEY_ prefix. Note that you can only use an XKB key
#: name for keys that are not known as GLFW keys.
#: Finally, you can use raw system key codes to map keys, again only
#: for keys that are not known as GLFW keys. To see the system key
#: code for a key, start kitty with the kitty --debug-input option.
#: Then kitty will output some debug text for every key event. In that
#: text look for ``native_code`` the value of that becomes the key
#: name in the shortcut. For example:
#: .. code-block:: none
#: on_key_input: glfw key: 65 native_code: 0x61 action: PRESS mods: 0x0 text: 'a'
#: Here, the key name for the A key is 0x61 and you can use it with::
#: map ctrl+0x61 something
#: to map ctrl+a to something.
#: You can use the special action no_op to unmap a keyboard shortcut
#: that is assigned in the default configuration::
#: map kitty_mod+space no_op
#: If you would like kitty to completely ignore a key event, not even
#: sending it to the program running in the terminal, map it to
#: discard_event::
#: map kitty_mod+f1 discard_event
#: You can combine multiple actions to be triggered by a single
#: shortcut, using the syntax below::
#: map key combine action1 action2 action3 ...
#: For example::
#: map kitty_mod+e combine : new_window : next_layout
#: this will create a new window and switch to the next available
#: layout
#: You can use multi-key shortcuts using the syntax shown below::
#: map key1>key2>key3 action
#: For example::
#: map ctrl+f>2 set_font_size 20
#: The full list of actions that can be mapped to key presses is
#: available here .
# kitty_mod ctrl+shift
#: The value of kitty_mod is used as the modifier for all default
#: shortcuts, you can change it in your kitty.conf to change the
#: modifiers for all the default shortcuts.
# clear_all_shortcuts no
#: You can have kitty remove all shortcut definition seen up to this
#: point. Useful, for instance, to remove the default shortcuts.
# action_alias
#: E.g. action_alias launch_tab launch --type=tab --cwd=current
#: Define aliases to avoid repeating the same options in multiple
#: mappings. Aliases can be defined for any action. Aliases are
#: expanded recursively. For example, the above alias allows you to
#: create mappings to launch a new tab in the current working
#: directory without duplication::
#: map f1 launch_tab vim

# kitten_alias
#: E.g. kitten_alias hints hints --hints-offset=0
#: Like action_alias above but, specifically for kittens. Generally,
#: prefer to use action_alias. This option is a legacy version,

#: cause all invocations of the hints kitten to have the --hints-
#: offset=0 option applied.

#:: zle clear-screen

#: Reload kitty.conf
# map kitty_mod+f5 load_config_file
# map ctrl+cmd+, load_config_file
#:: Reload kitty.conf, applying any changes since the last time it

#:: changed and require a full restart of kitty. You can also map a
#:: keybinding to load a different config file, for example::
#:: map f5 load_config /path/to/alternative/kitty.conf
#:: Note that all setting from the original kitty.conf are discarded,
#:: in other words the new conf settings *replace* the old ones.
#: Debug kitty configuration
# map kitty_mod+f6 debug_config
# map opt+cmd+, debug_config
#:: Show details about exactly what configuration kitty is running
#:: with and its host environment. Useful for debugging issues.
#: Send arbitrary text on key presses
#:: E.g. map ctrl+shift+alt+h send_text all Hello World
#:: You can tell kitty to send arbitrary (UTF-8) encoded text to the
#:: client program when pressing specified shortcut keys. For
#:: example::
#:: map ctrl+alt+a send_text all Special text
#:: This will send "Special text" when you press the ctrl+alt+a key
#:: combination. The text to be sent is a python string literal so
#:: you can use escapes like \x1b to send control codes or \u21fb to
#:: send unicode characters (or you can just input the unicode
#:: characters directly as UTF-8 text). The first argument to
#:: send_text is the keyboard modes in which to activate the
#:: shortcut. The possible values are normal or application or kitty
#:: or a comma separated combination of them. The special keyword
#:: all means all modes. The modes normal and application refer to
#:: the DECCKM cursor key mode for terminals, and kitty refers to the
#:: special kitty extended keyboard protocol.
#:: Another example, that outputs a word and then moves the cursor to
#:: the start of the line (same as pressing the Home key)::
#:: map ctrl+alt+a send_text normal Word\x1b[H
#:: map ctrl+alt+a send_text application Word\x1bOH
