For that you could modify the 'Endnote Reference' Style to have, say, a bold font and yellow shading.
Yes, how sloppy of you

Rather than complicating the macro further, you could use a wildcard Find/Replace with:
Find = (\<)([!\>\<]{1,})(\>)


Replace = {\2}
to change the '<*>' strings you don't want converted to endnotes to '{*}' strings (use something other than '{' and '}' if those characters are already in use), stepping through the Find/Replace process. Then run the macro. If you want to get the '<*>' strings back again afterwards, simply reverse the Find/replace process:
Find = (\{)([!\}\{]{1,})(\})
Replace = <\2>
and this time you won't need to step through.

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!
