Best tip I have gotten! Thanks! Works for Music too, so I presume it works for everything. Thanks again-It is taking me a while to convert from opaque Windows, but it is worth it. OS-X has so many extremely helpful features that I would never even think to look for in Windows.

Some Windows users say the reason that they don't like Macs is because they can't "meddle around". If they only knew all the subtleties in the powerful and wonderful Finder.
