[Vimperator] Question about Ctrl-[ as ESC

[mwastrod]

Hey Vimperator list,
	I am happy that this firefox mod has come along well. Unforetunately  
(or foretunately) my new work computer is a macbook pro. Which means,  
well, that my escape key doesn't seem to do anything right. It won't  
send an esc signal to any of the other applications, much less the  
vimperator. Is there a way to map Ctrl-[ to ESC? Ctrl-[ works in my vim.

Thanks!

Matt
