What the above posters are talking about can be done in Elements as well, where I do mine. It doesn't help for those shots already loaded to FAA, however. I tend to do a lot of copying and pasting keywords into multiple photos if they are all relevant. Sometimes I will cut them out of the keywords section, paste into a Word document, edit them there and then repaste them into the keywords section. It's easier for me this way to edit and cut out duplicates.
