All screen commands are prefixed by an escape key, by default Ctrl-a (that's Control-a, sometimes written ^a). To send a literal Ctrl-a to the programs in screen, use Ctrl-a a. This is useful when when working with screen within screen. For example Ctrl-a a n will move screen to a new window on the screen within screen.
