I know this is incredibly lazy of me, and it would probably save more time just going to Apple>Sleep, but I do it so much, and every time I do it I wish I could just do apple+s (or something else because that's save). So does anyone know how I can do that? And what key is free? Is there a key that isn't used in any apps that I can assign as my quick sleep button? Say, maybe F13? Or F6 or F7... there's a lot of F#'s that I've never used.
