Wildcards in Find/Replace

[JKC]

Hi all,

I'm trying to write a macro that will create a list of acronyms found in
a document. The acronyms are all uppercase and surrounded by
parentheses when they first appear. E.g.

"The National Aeronautical and Space Administration (NASA) ..."

I'd like to pull the "NASA" out of this sentence. I thought the easiest
way would be to do a Find on the form (*) where * is a wildcard.
However, when using wildcards, apparently I can't search for "(" or ")"
because the combination of parentheses and wildcards invokes pattern
matching.

Any ideas on how I should proceed?

Thanks,
JKC
