I want to boldface and superscript a numbering system in a book that goes like this:

(1:1)
(1:2)
(1:3)

I also want to remove the parenthesis, as well. I've tried this:

Find: ([0-9]+:[0-9]+)

Replace: <b>^\1</b>

But that doesn't grab the parenthesis in the numbering as well. I'm stumped. It seems like an easy thing, but for the non-technical user, not so clear. Please help.
