Address Book: SEE WHICH GROUPS THEY'RE IN

If you have a contact that appears in more than one Group, you can instantly see which of your Groups this individual appears in by simply clicking on his or her contact and holding the Option key. When you do this, every Group that they appear within will become highlighted. This is handy if you want to clean up your Groups by deleting extra instances of people who appear in multiple Groups.
