Thanks for the immediate reply. Let me make sure I got it. If I want to add text to the existing caption or keywords fields of one or more images, I would select the images, clear the stationary pad, insert the text, check the checkbox and check the "+" box and apply. Let's say I already have IPTC data applied to selected boxing images and now I wish to add scores to the caption for a particular bout ... I would clear the IPTC pad, enter only the additional scores (with a couple of spaces in front), check the box and "+", select the appropriate images, and apply?
I'll go looking for the PDF .. thanks! [Edit: Got the manual and already found things I didn't know about!]
