On my laptop, I can only get mouse-2 and mouse-3 clicks, no mouse-1 clicks for some reason, and no modified clicks, e.g. alt-mouse-1. Still, it is possible to get at least two different clicks! I thought I would share it in case anyone else wants different click behavior like that too. And in case anyone has ideas on how to get modified clicks.
Best wishes,
John
