Force a change to a program's key bindings

Question

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) & I have to wait for my entire instance of Firefox to stop & 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?

Answer 1

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.)
