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.
