Force a change to a program's key bindings Is it possible to force a change to a program's keybindings?  E.g., instead of an menu action being invoked by Cmd-J it's Cmd-K?

The reason I ask is that Cmd-Q in Firefox drives me nuts.  I occasionally hit it instead of Cmd-W (to close a tab) &amp; I have to wait for my entire instance of Firefox to stop &amp; then restart.  I'd love to bind "Quit" to something ridiculous (or remove it all together).

My hope is this is in a resource file that's easily hacked?
No resource file hacking necessary; it's all built in to the GUI. And not only that, but Apple's even documented it:


Using global keyboard shortcuts 
Creating keyboard shortcuts for applications


(the above assumes you're on OS X 10.6 Snow Leopard, but everyone with a supported system should be by now.)
