Mac OS X Lion All-in-One For Dummies

From Mac OS X Lion All-in-One For Dummies by Mark L. Chambers

Lion power users have a number of tools that come in very handy for controlling a Macintosh efficiently, as well as maintaining the operating system to keep it running in top shape. Although the mouse or trackpad is your primary means of controlling Mac OS X, Lion also recognizes a wide variety of keyboard shortcuts for the Finder. Most of these shortcuts involve using modifier keys such as Command and Option, which carry their own symbols. Mac owners should also follow a regular maintenance schedule to keep Lion running trouble free.

Mac OS X Finder Keyboard Shortcuts

As you probably know, the Finder is the foundation that performs most of the important functions within Mac OS X Lion, including displaying windows, copying and moving files, and launching applications. What you may not know, though, is that lots of Finder keyboard shortcuts are available for you to use to get things done more efficiently (especially if you’re a Mac power user).
