Momentary switches are "high" while the control is held, and low when its
not. This subsumes what Tim describes as a trigger as you can detect both
the rising and falling edge.
The plugins I have that need MOMENTARY would only look for the rising
edge, but if/when host support becomes common I can imagine looking at
duration and the falling edge too.
