Mac Touchpad Tricks

From Macworld.com:

Depending on the Mac notebook model, there are up to 10 specialized trackpad functions you can use to make navigating the screen, Mac OS X and various applications faster and easier.

The trackpad options discussed in this article are not enabled by default; you can enable them all in System Preferences using the Trackpad tab of the Keyboard & Mouse pane. The exact look of this pane will vary depending on the Mac model and on the version of Mac OS X installed, but most will look something like the figure shown below. Some options require hardware support and thus are available only on specific models.
