I've never considered how such worked, so I don't know what I'm writing 
about (what else is new?) but I always considered it a function of the 
device (keyboard) not the OS.  I figured that the keyboard sent 
different characters, based on the keypad mode.

Never seemed important to know the inner workings ....
