Rekordbox Video Output Window Fullscreen Shortcut

Hey guys

So this is probably quite an unusual case but tonight I'm VJing at a venue where the decks are above a giant screen.  It's incredibly cool on paper but a nightmare when trying to set up.  If there's an easier way let me know but normally to setup the master out screen, I'll double click on it to create a small window box and drag that to the other display.  Once there, hit the fullscreen green button and bob's your uncle.  Quite an easy process when you can see what you're doing.  Tonight I'm going to have to do that completely blind and in the past I've had projectors in hard to see places too which have required the same guesswork, facetime communication from a friend or a little to the left little to the right instructions.

Surely there can be an easier way.  Is there a shortcut for this?  I couldn't see one in the menu so maybe it's a request feature.  Alternatively if anyone knows any software that can monitor your second display from the first that would also be a handy alternative.

Thanks for taking the time to read
