timer

[Tom Eugelink]

I have been pondering this as well, but would this do the initial delay and the quick repeat afterwards? Or should I use the first KeyFrame for the initial delay and a second KeyFrame for the repeat delay (which just jumps the timeline back to the first). I could wrap this into a real timer class then.

Real world: the user presses-and-holds the LMB over an arrow in the spinner control, and it must start incrementing; tak tak tak tak tak, maybe picking up speed or step size as the button is held.
