- How-to: macOS Key bindings. Key binding allow you to swap around the action of keys (or key combinations) on the Mac keyboard. The default key bindings for the Home and End keys in macOS are different to most other operating systems. To remaps the key bindings of the current user, edit the default keybinding file.

MacOS has a system-wide mechanism to let you define or modify the shortcut keys for text editing operations.
When you use a Windows (PC) keyboard on a Macintosh computer, the keyboard shortcuts that you use map to different keys. In particular, the primary key that is used in keyboard shortcuts in combination with other keys is frequently different. The following are the primary key substitutions on the Windows keyboard, and their Macintosh equivalents.
It lets you create keys to:
- Insert math symbols, emoji, or any template text.
- Move cursor by word, page up/down.
- Copy, cut, paste, undo, redo.
- select word, line, paragraph, select all.
- upcase word, lowercase word.
- new, open, save, etc.
- and more.
Key Config File
Create a file at
~/Library/KeyBindings/DefaultKeyBinding.dict
Create the “KeyBindings” folder if you don't already have it.
Copy and past the following:
Note: if you use Unicode Characters directly in the file such as♥, you must save the file using UTF-8 encoding.
Launch or restart TextEdit or other app to start to use your changes.
The syntax in general is this:
- keycode is a string that represents key press.
- actionCode represents what to do.

Sample File
Example of defining the {Home, End} keys to move to the beginning/end of line.
Here's example file for inserting Unicode characters with the ⌥option key. https://fdiszo.weebly.com/mac-app-review-sites.html.

Mac Binding Router
You can look at Xcode's keybinding file at
/Developer/Applications/Xcode.app/Contents/Resources/PBKeyBinding.dict
.You can view it here: osx_keybinding_xcode.dict.txt.Emacs Keybinding
Mac OS X by default support emacs keybindings. They are:
- Ctrl+f → move forward
- Ctrl+b → move backward
- Ctrl+n → move down a line
- Ctrl+p → move up a line
- Ctrl+a → beginning of line
- Ctrl+e → end of line
- Ctrl+k → delete current position to end of line
- Ctrl+y → paste
You can add more of emacs's
- Ctrl+space → set mark
- Ctrl+w → cut
- Ctrl+xCtrl+x → Swap cursor position to last mark
However, i don't recommend it. Emacs's keys is very inefficient and ergonomically painful.See: Why Emacs's Keyboard Shortcuts are Painful.If you like a efficient keybinding for text editing, try:Emacs: Xah Fly Keys.
Problems
Something this cannot do. For example:
- It cannot remap keys.
- It can't set a key such as F8 to type other keys such as ⌘command+c.
- It can't set a key to launch a app or script.
There are many solutions to these. See:Mac: Key Remapping, Keybinding Tools
Best is to get a programable keyboard. See:Programable Keyboards with Onboard Memory
