Karabiner

A while back I stopped using “jk” to exit Vim’s insert-mode, turning instead to the mostly-useless Caps Lock. I set it to be Control, then used Karabiner to turn it into a dual-purpose Control/Escape. Typed by itself, it’s Escape; in concert with another key it’s Control. The boost in comfort and productivity has been huge.

Bringing Escape closer to home feels like a more sensible solution, and I’m no longer typing “jk” all over the place when my fingers forget they’re not in Vim. The productivity gains, however, are largely the result of having a Control key that’s so accessible. It’s opened up my use of control-modified commands like Vim’s autocompletion and the shell’s reverse-incremental-search quite a bit.

To set this up on OS X, first go to the Keyboard pane of System Preferences and change Caps Lock to Control.

Then use Karabiner to send Escape when you type Control by itself.

* karabiner preferences -> "Change Key" tab
* scroll down to "Change Control_L Key (Left Control)"
* check "Control_L to Control_L (+ When you type Control_L only, send Escape)"

More Control

I recently took this one step further and turned my Return key into a dual-purpose Control/Return, giving me easy access to a Control key on either side of the keyboard.
