Thank you so much for the comments. I really wanted the commands to be actual morse code so I added the "a"gain command instead of a single dash. I actually had the z button clear the current morse code word in a more complex version of the game (where you had to type 'move' then 'forward' not just 'f'...image how slow that would be!!), then my wife was like..."isn't the whole theme only one...?" lol.
