Since this series on code cracking hasn't been as popular as I'd hoped, I've decided to make it even easier. :awww:
Here is a partial solution containing all the controll codes I've included in my code. Note, however, that some of these codes I haven't used.
20 |number/letter| toggle
21 |lower case/upper case| toggle
22 |shift| (once of upper case letter)
This should speed things up a bit. :up:
