Alright, 2 things:
First, No need to be an asshole I looked at the manual and NO where under Keyboard Shortcuts does it say F5, F6 etc selects the decks, You can look for yourself.

Second, I thought this was the forum for Resolume, you know.. A place to ask questions about the program, If my question about the program bothers you, I appologize.. Just don't let it stress you... Next time I'll ask my Resolume question on some other forum...
