  To make it appear, open your System Library CoreServices Menu Extras folder as described above, and double-click the Eject.menu icon. Thats it! The menulet appears.

  You'll discover that its wording changes: "Open Combo Drive,""Close DVD-ROM Drive," "Eject [ Name of Disc]," or whatever, to reflect your particular drive type and what's in it at the moment.

• HomeSync is another one that's new in Tigerbut you can use it only if some friendly neighborhood network administrator has set up Mac OS X Server at your office.

Or not automatically; this menulet's Sync Home Now command performs this synchronization on demand.

(Syncing is described in more detail in Chapter 19.) To find the "Show" checkbox : Open System Preferences . Mac, and click Sync.

• Text Input makes it easy for you to switch among different text input modes . You're probably most familiar with the normal keyboard. But what if your language, like Japanese Kanji, has hundreds of symbols in it? How will a 26-letter keyboard help you then?
