Safari Books Online is a digital library providing on-demand subscription access to thousands of learning resources.
You can open System Preferences in dozens of ways. Most people choose its name from the menu or click its icon in the Dock, but if you have a laptop, Option-volume key (one of the speaker-adjustment keys on the top row of the keyboard) or Option-brightness keys opens System Prefs, too. (These tricks open the Sound and Displays panes, respectively, but you can then click Show All or press
-L to see the full spread.)
Tip:
If you know the name of the System Preferences panel you want, it's even quicker to use Spotlight. To open Energy Saver, for example, hit -Space, type ener, and then press
-Enter. See Chapter 3 for more on operating Spotlight from the keyboard.
