Koffee

The Keyboard-Oriented File & Folder Explorer for Efficiency, or Koffee, is a no-nonsense alternative to Windows Explorer focused on VIM-style keyboard shortcuts, speed, and simplicity. It is built on .NET WPF, written in F#.

Why would I want to use this?

The goal of this application is to allow users to navigate and manipulate files and folders very quickly, almost at the speed of thought -- a speed only achievable via keyboard. If you've ever experienced the productivity boost that comes from learning and using all the keyboard shortcuts in an application (or learned to use the text editor VIM), you understand what a big difference it makes.

Installation

Koffee depends on Microsoft .NET Framework 4.8.1. You probably already have it installed. If you don't, go to .NET Framework 4.8.1 to download and install it.

From Chocolatey

choco install koffee

From Scoop

Koffee is part of the "extras" bucket. If you haven't already, add this bucket with scoop bucket add extras.

scoop install koffee

From Installer or Zip

Go to the releases page. From there, you can download and run Koffee-Setup.exe, which will guide you through the installation with a wizard. Or, if you prefer to install it yourself, you can download the zip file, unzip the app wherever you want and create your own shortcuts.

From Source

You will need to have installed:

• Visual Studio or VS Build Tools 2019
  • Make sure to select the components ".NET SDK", ".NET Framework 4.8 targeting pack" and "F# compiler"

Steps:

• Clone this repository

Using Koffee

First of all, take your hand off of the mouse because this is a keyboard tool! Once you're familiar with the hotkeys, you'll be navigating your files more quickly than you ever could with a mouse. If you're familiar with the text editor VIM which is popular among programmers, you should feel at home.

The Basics

A capital letter indicates that the letter key is combined with Shift.

• j to move the cursor down
• k to move the cursor up
• h to go up to the parent folder
• l to open the file or folder under the cursor
• Enter to open selected files or item under the cursor if nothing is selected
• Shift + Enter to open the "Open With" dialog for the selected file
• H to go back in navigation history
• L to go forward in navigation history
• gr to go to the root directory (Drives)
• Tab to switch between the main view and the path box
• ? to open the Settings window, which displays the hotkeys for all commands.
• Esc to cancel actions, searches, path input, etc.
• Ctrl + w to exit

Advanced Navigation

• Scroll quickly
  • Ctrl + j and Ctrl + k move the cursor by half-pages at a time.
  • gg (press g twice) jumps to the first item, and G jumps to the last item.
• Find / Jump to item:
  • Press f then the beginning of a file or folder name. The cursor will jump to the first matching item as you type (not case-sensitive).
    • Press ; during or after a Find to jump to the next matching item.
    • Press Enter to open the selected item and close Find.
    • Press Esc to close Find.
  • Press F to start a "multi" Find, which stays open when opening folders.
• Search:
  • Press / to start a search. This will move your cursor to a search input at the bottom of the window where you can enter space-separated search terms. The list will be filtered to matching items as you type.
  • Press Ctrl + i to toggle whether the search is case-sensitive.
  • Press Ctrl + r to toggle regular expression mode instead of term matching.
  • Press Ctrl + s to toggle sub-folder searching. A progress bar will show while results are loaded in the background.
  • Press Up to go back through previous searches and Down to go forward.
  • Press Shift + Delete when the previous searches are shown to delete the selected search history
  • Press Enter to close the search input and navigate the results. The current search filter will be shown at the bottom of the window.
  • Press Esc when the search input is open or when a search filter is active to cancel the search.
  • Press n to repeat the previous search when no search is active.
• Bookmarks
  • Set a bookmark for the current location by pressing m. The existing bookmarks are shown. Enter any character to set a bookmark to that character. Upper-case letters are distinct from lower-case letters.
  • Go to a bookmark by pressing '. The bookmarks are shown. Enter a character to activate the bookmark set to that character.
  • When viewing bookmarks, press Delete then a character to delete the bookmark set to that character.
• Saved Searches
  • To save an active search (the search input must be closed), press m. The existing saved searches are shown. Enter any character to set a saved search to that character. Upper-case letters are distinct from lower-case letters.
  • Activate a saved search by pressing `. The saved searches are shown. Enter a character to activate the saved search set to that character.
  • When viewing saved searches, press Delete then a character to delete the saved search set to that character.
• Sorting
  • Press sn to sort by name, ascending then descending.
  • Press sm to sort by modified date, descending then ascending.
  • Press ss to sort by size, ascending then descending.
• Path Box Suggestions will appear when typing in the path box.
  • When no slashes are in the path box, files and folders that you have opened in Koffee are searched. Items starting with the first search term are shown first, then other matches sorted by most recently visited.
  • When a path is in the path box, everything after the last slash is used to search the folder before the last slash. For example, typing "C:\Windows\sy 32" would suggest "C:\Windows\System32".
  • When suggestions are shown, use the up and down arrow keys to select a suggestion. When there is only one suggestion, it is selected automatically.
  • Press Tab to fill in the path box with the selected suggestion and continue typing, or press Enter to open the selected suggestion.
  • When suggestions from history are shown, pressing Delete will remove it from the list and history.

File & Folder Manipulation

• Selecting
  • If there is no selection, actions apply to the item under the cursor
  • Press Space to toggle whether the item under the cursor is selected
  • Press Shift + Space to select or unselect the range of items between the previously toggled item and the cursor, inclusive
  • Press Ctrl + a to select all items in the current location
  • Press Esc to deselect all items when there is a selection
• Create File or Folder: Press o to create a file or O to create a folder. Type in the name of the new item and press Enter.
• Rename: There are several ways to start renaming the currently selected file or folder.
  • Press i to start with the cursor at the beginning of the name
  • Press a to start with the cursor at the end of the name, before the extension
  • Press A to start with the cursor at the end of the extension
  • Press c to start with the name (without extension) selected so that typing will replace the name
  • Press C to start with the full name selected
  • When you are done editing the name, press Enter
• Move / Copy / Shortcut
  1. Press d to start a move, y to start a copy, or Y to start a shortcut of the selected item(s). The item and operation ("yank register") will be displayed in the lower-right corner of the window.
  2. Navigate to the destination folder and press p to "put" (move, copy, or create a shortcut of) the item(s) there.
     • A copy to the same folder will append "(copy)" to the name.
     • If at least one item with the same name already exists, you will be prompted to overwrite them. If you choose to overwrite a folder, the contents will be merged (existing files in the destination with the same name will be overwritten, but the others will remain).
  3. You can cancel a move or copy in progress by pressing Esc. Performing a Redo (see below) will resume the action.
     • If you decide not to perform the put and want to clear the yank register, you can do so with Alt + y
• Clipboard:
  • Press Ctrl + x to cut the selected items to the Clipboard.
  • Press Ctrl + c to copy the selected items to the Clipboard.
  • Press Ctrl + Shift + c to copy the paths of the selected items to the Clipboard.
  • Press Ctrl + v to paste items that were cut or copied into the Clipboard (from Koffee or another app) to move or copy them to the current folder.
• Delete
  • Press Delete to send the currently selected item(s) to the Recycle Bin. If the item cannot be recycled, an error message will be shown instead.
  • Press Shift + Delete to delete items permanently. You will be prompted to make sure this is what you want to do; press y to proceed with deletion or press n to cancel.
  • You can cancel a recycle or delete in progress by pressing Esc.
• Undo / Redo Action
  • Press u to undo the last file or folder action (creating, renaming, moving, copying and deleting). The status bar will report the action that was undone. Since deletions cannot be undone, the status bar will simply report the deletion that cannot be undone.
  • Press U to redo the last action that was undone or to resume a cancelled action. Note that performing any action after an undo will clear the redo list.
  • You can cancel an undo or redo in progress by pressing Esc. You can resume the undo or redo by invoking it again.
  • Press gu to display undo / redo history. Press it again or Esc to close it.
