I think that the reason you will never see a control key for a mac plus is
that the hardware interface uses some of the control characters as interface
control characters.  Basically this means that there is NO way using current
system software and mac plus hardware to send certain characters over the 
keyboard connection.  A solution would be to use an INIT to supplant the
system keyboard driver and use a new keyboard which would "quote" or "escape"
the control characters.  This would probably not work in all cases.  I base
my thoughts on information from the ancient "Underground Inside Macintosh"
paper.
