Thanks a lot, Paul/macropod. I'll see if I can make that work. I need to find all instances of [A-Z][A-Z]-[0-9] in a doc. (and get surrounding characters, if present, that are similar*) and somehow list them (either by deleting everything else in the doc or copying them into a blank file). I'd tried the Find functionality, but I couldn't get it to do what I needed. I'll keep experimenting.
*e.g., BC-3, ABC-5, BC-003, DA-378-A
