Apple has put up a page in its “Support section”:http://support.apple.com/kb/HT3458 describing the various combinations of button pressing to work the new “iPod shuffle”:/2009/03/ipod-shuffle-slimmer-smaller-smoother/.
Getting the various combinations of double or triple clicks and/or hold the center buttons will probably be a frustrating experience in the beginning. Remembering them will probably another story.
Do bookmark that page if you are going to be a new iPod shuffle owner.
