Here's where you become more sophisticated. You have just illustrated
one of my pet peeves: special casing `?' in control code functions.
Why do you think DEL is `^?'? There is a function that will map both
letters AND the apparant special case `?': char XOR 64. Of course,
this forces you to type ^A instead of ^a, so it is more useful as an
output transformation than as an input one: ^a maps to `!'!

It is amazing how many people don't know this trick, so don't feel bad.
