From OS X Yosemite All-in-One For Dummies

By Mark L. Chambers

Yosemite power users have a number of tools that come in 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 OS X, Yosemite also recognizes a wide variety of keyboard shortcuts for Finder. Most of these shortcuts involve using modifier keys such as Command, Control, and Option, which carry their own symbols. Mac owners should also follow a regular maintenance schedule to keep Yosemite running trouble free.
