command q doesn't work
command q no longer seems to work for me. it doesn't quit from any of the applications. (tried it in safari, firefox and a other apps)
command w doesn't close the tab. command n doesn't open a new window and the list goes on.
command a does work! selects all in the page.
the keys are all good, nothing wrong with the keyboard.
what/where can i check for the default behavior of these keys? i've tried resetting to defaults in the keyboard shortcuts under 'system preferences'.
help!
