I didn't know about that option key trick (there sure are plenty of 'em) in Address Book so thanks for that tip. Since migrating to Apple Mail from Mulberry (my long-time favorite IMAP client whose company filed for bankruptcy) I've been started using Address Book more often and paying attention to related hints here. My primary contact list is still on my Palm PDA, awaiting a synchronization with Address Book via Missing Sync once I have enough time for the tedious post-sync task of finding/fixing any "mistransferred" entries (which I'm sure there will be).

Watch out for one of the new 'features' of Missing Sync.

It handles groups from Address Book, but really only can handle each Address Book entry being in one group.

This is pretty crap, but you can live with it - I've had to change to using Smart Groups and special additions to the Notes section.
