What I did to implement a control key on the Mac Plus was to provide additional
functionality to the existing calls.  In other words:
  (in C)
  if ((eventMask == 0) && ((theEvent & 0xF8000000) == 0xF8000000)
    /* do my code */
  else
    /* standard event call */

This allowed me to take an "illegal call" and make it a "call to my function"

Note that I don't condone this, it just was convenient for my application
(converting the command key to a control key).
