	Although you COULD do it with a KCHR resource, folks running with their own keyboard layouts - like ANYONE with a non English/Roman system - would get REAL UPSET at you...
	The correct way to do this is to patch _KeyTrans which is the trap which handles the 'mapping' of raw keycodes & modifiers into the events that the program gets via GNE/WNE.   In the patch just check for you set of modifiers and then switch it to the control key instead...The only caveat of this whole process is that the Process Manager will swap your patch out EVEN DURING A MINOR CONTEXT SWITCH, so you have either a) live it with or b) munch the in memory KCHR to handle it.  b is the correct, though diff







icult solution, which we do for MicroPhone II, however a will work for most.
