Some control keys (such as TAB or ESC, I don't remember atm) are added as empty half-width
letters into the editor instead of being handled by the application as control keys.
The editor probably should just accept only well-known character keys as chars instead
of trying to be smart and accepting everything in 0..255 and then filtering out control
keys on an individual basis.
Original report by me.
