1. A is deprecated, B is current.
2. B has much more flexible, and safer.

With B, arg 1, arg 2, and (?arg3) can be sequences as well as atoms.
So, to add an association of buttons 1,2,3 with a click event "whatever":
setHandler({button1,button2,button3}, w32HClick, routine_id("whatever"))

And to add an association of both the key down and key up event for the 
window1:
setHandler(window1, {w32HKeyDown, w32HKeyUp}, routine_id("whatever"))

And to remove any existing w32HClick events from ButtonXX and enter a new 
one:
setHandler(PushButtonXX,w32HClick,{-1,routine_id("whatever")})

Okeydokey?
