Excellent advice, and I thank you!

Actually, I felt retroactively dumb for having come back with the bit about how to hi-light an endnote reference, since I do know how to format a style or two; but had my head wrapped up in the macro at the mome. I figured that one out as soon as I'd backed off of posting the message.

But the search & replace is helpful, and rounds out my need, as it were, so thanks again!
