I assume you're using TeXShop 1.35.   When you are using Regex Find, 
there is an option in the "More Options" pane called "Delimit by 
Whitespace". When this is checked the Find searches for each word 
separately. So if you search for:

blah whatever

the search will find "blah" and "whatever" but not "blah whatever". 
This is the same thing as searching for blah|whatever using regex. This 
"Delimit by Whitespace" option works for the various search syntaxes 
(ruby, perl....) and for "Simple Matching" (regex off)

In your case, if you had "Delimit by Whitespace" enabled and regex off, 
it would find "(" and replace it with "()" and ")" and replace it with 
"()". So result would be "() ()" --- kind of a bummer.

The regex panel is pretty cool. Very flexible. And a very sharp knife. 
I did something similar to this on day one.

Undo does work, but you have to switch to the text window to activate 
it. This is different from the regular system-wide Find.

Take care,

Bob
