I assumed you were talking about CW.  If you are, then the Key and 
unKey commands send and shut off a CW carrier.  If you use these 
functions in CW mode, they won't do anything but key up a steady 
carrier.  

In voice modes, they act like you'd expect PTT to act, placing the 
radio into transmit mode, etc.  So they can be used for digital modes 
if you're sending audio tones to the transmitter in AFSK mode, etc.

Not sure what the effect is in FSK, since I haven't tried it in that 
mode.
