The mighty mouse only has one button! Assuming you are using a Mac mouse
Press CTRL and click to get the right click options!
Alternatively, if you just plug in a regular PC mouse, it will be recognised and work just as it would on a PC without the need to fiddle with the options.Assuming you're using a Mighty Mouse, go to System Preferences > Keyboard & Mouse. Click the mouse tab and from there you can configure the left, right, centre and sides of the mouse
