For my ELS I have a STOP button.  Press it and it is like a feed hold.  The 
current move completes and then the system stops.  So it doesn't stop in the 
middle of threading but moves the Z until it's finished that pass and then 
stops.  If START is pressed again it then withdraws the tool (X axis) and 
continues back to the begin position.

But if you press and hold the STOP button for a second or so it stops motion 
now.  And if the tool bit is in the middle of threading you will trash the 
thread.  But if it's headed in the wrong direction because you entered a 
Positive END position rather than a negative one from the 0 start position then 
pressing and holding STOP prevents it from going too far in the wrong direction.

One button, one finger, two operations depending on how long it's held.
