hmmm, you would like to have a double clic behaviour don't you?
the algorithm is the same with mouse clicks. but you have a constraint:
the double click time gives the maximum rate at which you can call the
simple click command, and it also adds latency.
because the simple click command won't start until the double click
timeout is reached...
