One of the more common question my buyers asks me about his new Mac is, "Where can I get tutorials or learn to use the trackpad gestures?"
Well, you can obviously get it everywhere in the net now. Youtube for one have loads of them.
But the most accessible ones is right there in your Mac.
Just go to your System Preferences, choose Trackpad.
Then in there, point your cursor to whichever gesture available and the tutorial will show you briefly how it works.
Cool eh?
Enjoy.
