I'm not sure I understand what you're doing here. Why are you making it 23 columns instead of 22? There are only 22 physical columns on the keyboard. Why are you moving 109 to column 22 and 95, 59, and 37 to their own column? A commit description indicating what you're trying to accomplish would be helpful.
