Is there a keyboard shortcut to close the Application Frame in CS6 Mac? Mousing to menus or click on

nothing works close window except mouse/clicking... don't being in background when i'm working in other apps.

you realize can disable , not have application frame come default, right?

go window menu (i think is), uncheck application frame, quit photoshop (to ensure preference change saved). next time comes shouldn't seeing application frame @ all.
