iPad Tip 46 (and iPhone) Customize Mail Swipe

Mail has enhanced swipe gestures for quickly dealing with messages by swiping left or right on them. You can customize these options via Settings > Mail, Contacts, Calendars > Swipe Options. You can choose from None, Mark as Read, Flag, and Archive. For Swipe Left, your choice appears in the list of shortcuts that swiping partway reveals, but swiping all the way deletes a message.
