This is the difference. The virtual key code for a key does not
change when the shift key is down. It's the combination of seeing the
virtual key code for the shift key and a letter key that allows
TranslateMessage convert virtual key codes in WM_KEYDOWN/WM_KEYUP
messages to the WM_CHAR messages containing the 'character' to be
used.
The virtual key codes for the letter keys are (on an English keyboard)
the ASCII codes for the UPPER case letters.

I think if you use ord 'Q' rather than ord 'q' your code would work (untested).
