I appreciate the advice quant. But no joy here. Using your ideas, I did find one item that had the "bad" user-defined keyword and unchecked it, but the keyword persists and all searches that I try, including the ones you suggested, turn up hundreds of hits.
Having to visually inspect each one in a retail way, i.e., individually to see if it has the keyword is an exercise in frustration. And were this mission critical instead of just moderately irritating, I'd pay the price.
As it is, I guess I'll just live with being annoyed until such time as I revamp my infobase completely or that Kinook sees things my way about giving me a delete button for user defined keywords in the keyword dialog. (hint hint)
Thanks again.
