Despite gaining proficiency with a track-pad as an alternative to a real mouse, I missed the mouse-wheel. This little innovation makes scrolling through documents a breeze, and I often plugged a mouse into my laptop to get the functionality.

Of course, the Mac has a solution. The track-pad of a Mac Book an detect two fingers at the same time, and if you hold one finger still while sliding the other then it acts like a mouse wheel – easy peesy scrolling back. Another bonus is that it’s vertical and horizontal scrolling, so it’s even better than a mouse wheel. Cool.

When I stumbled across this I did a bit of digging, and found another little utility – hold down the CTRL key at the same time and the display zooms in and out around the mouse, handy for checking out fine detail or when the eyes are getting a little tired.
