Shortcut button? for playing full screen on laptop?

I'm trying to determine if there is either a button you can create or keyboard shortcuts you
can hit that will change from the Final Cut Pro interface to playing back the timeline
full screen on your laptop or external monitor.

In other words, what you would normally do manually by going to the VIEW dropdown and
choosing - VIDEO OUT - FULL SCREEN.

Can that be accomplished via a button you create or keyboard shortcut combo? I don't see
it in the button list or any keyboard shortcut indicators on that particular dropdown command.

I'm trying to do with with FCP6 but I also have FCP7 available to me if it's easier to accomplish there.

Thanks in advance for any assistance.
