Yes, it is what I wanted to hear, or more precisely, some sort of pointer or 
"how to" about how I can do that.

Specifically, the problem is that the -clickCount property of an NSEvent is 
only applicable to mouse events, not touch events. So what's the right way to 
trap this specific gesture? I have read the various touch-input documentation 
but nothing became obvious.
