One of the great features of OSX in the support for dual button and scroll wheel mice.

On any standard OSX window the wheel will scroll your view up and a list, but hold down the shift key at the same time and you can scroll horizontally too.

Logic takes this a stage further and let's you add the **** key at the same time to control zooming. Hey, who needs that 30" cinema display when it's this easy to scroll around.
