I have an indesign para style where I have a character style nested to a colon. I'd like to have a grep style that states "whenever you encounter text in parenthesis, italicize the text (along with the parathensis)". I thought it would be [\(\l\u\)] but that didn't do it. Any help would be appreciated.
Your try consists only of a *character set*, that is, a list of matching single characters. Hence it doesn't work -- *all* of each single character in your set, uppercase, lowercase, and parentheses, are matched, one at a time.
Try this instead:
It's left to right: open parens, any character, lots of them, but not too many, closing parens.
