can't get Alt key to work as Meta #2922

What Operating System(s) are you seeing this problem on?

Windows

Which Wayland compositor or X11 Window manager(s) are you using?

No response

WezTerm version

wezterm 20230102-155114-67896f67

Did you try the latest nightly build to see if the issue is better (or worse!) than your current version?

Yes, and I updated the version box above to show the version of the nightly that I tried

Describe the bug

I'm using the current nightly Windows build of WezTerm to connect to my linux workstation. For some reason when I use the Alt key in a program like emacs, it isn't registered as a Meta keypress, much like Esc is. For instance, M-w is the copy command in emacs, and using Alt-w doesn't work. I didn't see any details on the website about configuration options that would correct this issue, and times I've used WezTerm in the past didn't require anything special from what I recall. Below is the debug_key_events output when pressing Alt-w.

To Reproduce

No response

Configuration

local wezterm = require 'wezterm'
return {
    color_scheme = "Gruvbox Dark",
    font = wezterm.font("Hack Nerd Font Mono FC Ligatured CCG"),
    font_size = 12,
    line_height = 1.1,
    default_cursor_style = "BlinkingBar",
    hide_tab_bar_if_only_one_tab = true,
    bypass_mouse_reporting_modifiers = "SHIFT",
    send_composed_key_when_left_alt_is_pressed = true,
    send_composed_key_when_right_alt_is_pressed = true,
    enable_scroll_bar = true
}

Expected Behavior

Try changing https://wezfurlong.org/wezterm/config/lua/config/allow_win32_input_mode.html to false

wez commented 1 year ago

Also, either one of send_composed_key_when_left_alt_is_pressed or both of send_composed_key_when_left_alt_is_pressed should be set to false to avoid using the OS alt-gr style composition when using the corresponding alt key, and allow wezterm to encode it as a meta key.

bsferrazza commented 1 year ago

@wez unfortunately that didn't work. I originally wasn't setting the send_composedkey* values and leaving them at the default and it was still not sending Meta. I also tried using no config and setting allow_win32_input_mode to false and that didn't help. Here's the debug_key_presses with that set to false.

I do use mosh. I'm not sure if that could somehow be contributing to this issue, but doesn't seem as though it would.

wez commented 1 year ago

It looks like wezterm never receives a key down event for alt-w. Do you have some other software installed on the system that handles alt-w, or that might do things when the alt key is pressed?

bsferrazza commented 1 year ago

@wez You were absolutely right. Used a Windows program called HotkeyDetective and found out that Alt-w was being processed by some Dell Display Manager tool. Thanks for your help.
