Morphic is a GUI. Its input handler should not have to deal with 
host-specific modifiers and just map keycodes to selectors (commands).

VM input plugin will parse CTRL+Q into keycode 16r11 to Squeak. Morphic 
input handler will map this keycode to, say, #quitKey. so you should 
just be able to write:

MyMorph>>quitKey
	self terminateApplication

Later if we want to allow ALT+Q also to quit, then we just need to add a 
single entry to the Morphic keycode map.

It happens to me too, especially when working late into the night ;-).

I think of a keycode as a SmallInt (or sequence of SmallInts) that 
encodes a Character or Symbol (selector), just like a machine word 
encoding integer or oop.
