How to remap Esc to Caps Lock in Janus (VIM)

Question

How do I remap the esc (escape) key on my Mac (Mountain Lion) for Janus (VIM).

What is the command?

And in what file do I insert this code?

Answer 1

Remapping Caps-lock to Esc can't be done in Vim itself (or in Janus) because Vim is unable to recognize the Caps-lock key anyway.

You'll need a third party tool for that:

• Ukelele
• KeyRemap4MacBook
• PCKeyboardHack

Maybe there are others.
