How to map CAPS LOCK key in VIM?

Question

I'm using GVIM under Windows. And want to map CAPSLOCK to Ctrl+^

Any way to do this?

Btw, I see tons of samples over the web how to swap CAPS and Esc using registry hack, but none of them use VIM map command, instead external tools and registry changes.

Answer 1

Linux? With X, use xmodmap to alter the key mapping, e.g.

xmodmap -e 'clear Lock' -e 'keycode 0x42 = Escape' 

Will map Esc to the CapsLock key. Google for more examples.

Answer 2

If your intention is just to avoid working outside of Vim, you can put these lines in your .vimrc:

au VimEnter * !xmodmap -e 'clear Lock' -e 'keycode 0x42 = Escape' au VimLeave * !xmodmap -e 'clear Lock' -e 'keycode 0x42 = Caps_Lock' 

The first line maps escape to the caps lock key when you enter Vim, and the second line returns normal functionality to caps lock when you quit.

This requires Linux with the xorg-xmodmap package installed.
