The other right click.....if you adjust your settings then you can right click using the touch bad by putting TWO fingers on the touchpad and then clicking the button. Personally I find this simpler than hitting the control button. Also, if you hook up a might mouse to it you can enable it to use two button features even though there aren't actually two buttons. Works like a charm.
You just need to go into System Preferences->Keyboard and Mouse
On the trackpad tab check the box about taping the trackpad with two fingers for secondary click.
On the mouse tab just change the drop down on the right side of the mouse diagram to say secondary button.
