Fill Out Forms Quickly

Fill Out Forms Quickly

Enter it once. Use it practically everywhere. One of the brightest gems in Mac OS X, Address Book integrates with Safari, Mail, iChat, iCal, and other applications. And it syncs effortlessly with iPhone and iPod — so you can take contacts wherever you go.

Because it integrates with Safari, you can use it to fill in forms when you’re shopping online. Here’s how:

  1. Open Safari and choose Preferences from the Safari menu.
  2. In the Preferences dialog, click the AutoFill tab and click the checkbox next to Using info from my Address Book card.
  3. Click the Edit button to view, and if you’d like, modify any of the information on your Address Book “My Card”.

Next time you shop online, Safari will retrieve the information it needs from Address Book.
