SORTED - actually, yes - it was easy.
I missed what you where saying with "Go Address Book" and took it to be just highlight somebody in the contacts pane.
Thanks timmcat and FJJP - another lesson learned.
What I wanted, FJJP, was to sort the bunch of CAA contacts into one folder, buddies into another, Ppruners into another etc. etc. - rather than scrolling down through them all to get to the right person.....as you say "just for storage and neatness".
Thanks again - sorted.
