This one is new to me although it may have existed for some time. You need a mice with a wheel to achieve this trick. Go into Keyboard and Mice system preferences and click the zoom option at the bottom of the window. You have the choice of a key modifier (Control by default). Then, whenever you press the Control key, you can zoom in and out of the screen using the mice wheel. This is impressive and quite useful when you have a big screen to read on the fly those tiny characters.

Actually, the trick has been around since 10.point.something. But it is a handy trick!

It works just fine without the mouse. Just press ctrl (or whichever key modifier you have set), and drag as you normally would to scroll (two fingers, by default). Think of the mouse pad as the “wheel” on a Mac Mighty Mouse.

If you go to the Universal Access tab under your System Preferences, then you can choose to enable zoom by pressing Command-Option -+ and Command-Option- -. This works great on computers without mouses with scroll wheels and without two-finger scroll trackpads as mentioned above.

Is there a quick way to unzoom? for example pressing Esc does not undo the zoom, but is there another key combination?
