Enable f12 shortcut for firebug

I was wondering, how to enable the F12 shortcut key on OS X for Firebug? I don't really use Dashboard, so I'm more than happy to disable it.


You can disable or change the shortcut for Dashboard in System Preferences - Mission Control for Mac OS X 10.7+. In older versions of Mac OS X the appropriate preference pane should be called Exposé.

After you changed the shortcut, it should correctly activate Firebug instead when Firefox is active.
