My DefaultKeyBinding.dict for Mac OS X

DefaultKeyBinding.dict

/* ~/Library/KeyBindings/DefaultKeyBinding.Dict

This file remaps the key bindings of a single user on Mac OS X 10.5 to more
closely match default behavior on Windows systems. This makes the Command key
behave like Windows Control key. To use Control instead of Command, either swap
Control and Command in Apple->System Preferences->Keyboard->Modifier Keys...
or replace @ with ^ in this file.

Here is a rough cheatsheet for syntax.
Key Modifiers
^ : Ctrl
$ : Shift
~ : Option (Alt)
@ : Command (Apple)
# : Numeric Keypad

For a good reference see http://osxnotes.net/keybindings.html.

NOTE: typically the Windows 'Insert' key is mapped to what Macs call 'Help'.
Regular Mac keyboards don't even have the Insert key, but provide 'Fn' instead,
which is completely different.

"^\UF702" = "moveWordLeft:"; // ctrl-left
"^\UF703" = "moveWordRight:"; // ctrl-right

This doesn't work on BigSur. Anyone know the correct way?

@jlahijani These have changed to moveWordBackward and moveWordForward.

Odd. Those work for me on Monterey without changing "left" or "right" to "backward" / "forward"

🤔

Need to remove the default control-left/right shortcuts in mission control in Settings -> Keyboard -> Keyboard Shortcuts -> Mission Control -> Mission Control
