Why Does the MacBook Air Have an Eject Button? We Explain the Mystery

Looking at the MacBook Air keyboard raises one question for those with attention to detail. Why is there an eject button if the MacBook Air has no optical drive.

The obvious answers might be to standardize keyboards or to allow users who buy an external USB optical disc drive to eject it. But there is a third less obvious answer that might also be more useful. The eject button is used for some handy OS X keyboard shortcuts.

  • Eject alone – ejects the optical disc caddy if one is present
  • Option-Eject – when a send drive is connected, it ejects the disc caddy
  • Option-Command-Eject – puts computer to sleep
  • Control-Command-Eject – restart computer after offering to save all open documents that are unsaved and close applications
  • Control-Option-Command-Eject – same as previous but shuts down instead

Apple has a complete list of OS X keyboard shortcuts.

Another useful keyboard shortcut for MacBook Air users includes one to move up or down a page since the computer’s keyboard doesn’t have those buttons. Use the Fn+Up/Down Arrow for up/down a page. By the way the left/right arrows do the same when paired with the Fn key.

Shift+Command+I opens your iDisk space, helpful for those with tiny SSDs like the 11-inch MacBook Air with only 64GB.

And for all Mac users, one of the most useful keyboard shortcuts is the Command+Space to open the Spotlight search. Use this to look for documents, Internet bookmarks or more importantly to find an application to launch.
