Using Caps Lock as Esc in Mac OS X

Question

How do I make Caps Lock work like Esc in Mac OS X?

Answer 1

The only thing I know how to do is to map Caps Lock to Control, or Option, or Command. This can be done via the Keyboard & Mouse pane of System Preferences. Click on "Modifier Keys" on the bottom left and you'll be able to remap Caps Lock, Control, Option, and Command, to any of those.

@Craig: This suggests that Caps Lock can be used as a normal -- that is, non-toggle -- key. On my MacBook, since I have re-mapped Caps Lock to Control, the Caps Lock light never lights up. It simply acts like the Control key.
