Both Mac and Windows fans have spent years collecting bits of lore-a keyboard shortcut here, an undocumented double-click there-and then Mac OS X 10.2 came along. It may be the world's best operating system, but it has a personality all its own.

As it turns out, Mac OS X harbors just as many delicious secrets as any system that came before. You just have to know where to find them. And Mac OS X Hints: Jaguar Edition is the guide you need.

Inside, you'll find 560 high-octane secrets in every conceivable category:

• Desktop and Finder. How to shut down using only the keyboard; use an animated screen saver as a desktop picture; and jump to System Preferences with a keystroke.
• iApps. How to burn six hours of iTunes music onto a single CD; merge calendars in iCal; and prevent iMovie 3 from applying the Ken Burns effect.
• Mac OS X programs. How unlock 32,000 secret Unicode symbols in each font; rename the System Preferences panels; add an "Email this page" button to Safari; and make Mail announce, in a cute British accent: "Mail has arrived, O all-wise master."
• Mastering the system. How to share Web bookmarks between Mac OS X and Classic; connect to your Mac from the road; and make your iDisk work ten times faster; and.
• Terminal. Unix fiends have never seen anything like the 105 pages of Terminal brilliance in this book. They explain how to save Terminal commands as Finder icons; put background programs to sleep; wake a sleeping Mac via the Internet; unearth the secret emacs adventure game; set up a message board on your Apache-based Web site; and more.

With authority, humor, and 440 illustrations, Mac OS X Hints: Jaguar Edition brings you insight, surprise, and delight at every turn. And that, after all, is what the Mac is all about.
