Also just read this from another thread, also a very clean suggestion:

RFE: Button COMP > New Button Types "Pulse" and "Pulse Up"

True, you get a 1-frame pulse by setting the Button COMP to Momentary, and adding a Logic CHOP set to Rising Edge. Nonetheless, adding a pulse option to Button is on our todo list.
