Dear Mallardbro,
Sticking true to the whole letter format, I'd like to ask you a question. Upon reaching said step, what is the process you did towards finding out beyond trial and error? Currently I have them narrowed down to basic functions and upon restarting, the buttons seem to act the same but the symbols change location.
Yours truly,
