Did you know that you can adjust your trackpad settings? Under your system preferences, click on "trackpad". This opens up a menu that has three parts.
The second part is Scroll & Zoom. This is pretty self explanatory (and it has supporting videos for you). You can select which direction you want to scroll and how you want to zoom in and out. You can also check the rotate box which allows you to rotate with two fingers!
The last part is More Gestures. I think this is my favorite bit about the trackpad! There are tons of quick trackpad gestures. Here are my favorites:
Mission Control: Swipe up with three fingers.
Show Desktop: Spread with thumb and three fingers.
Swipe between full-screen apps: Swipe left or right with four fingers.
Launchpad: Pinch with thumb and three fingers.
