You are having a lot more luck than I am finding the stuff

I haven't tried Notepad++ (even though it is installed on this machine). What I have been doing is copying the section of code I was interested in into a vim window. That allowed me to find mismatched pairs, but I would rather have them highlighted when the cursor wasn't on the character.

At least now I have better starting points than the poorly cobbled together idea in my head.

Thanks for the help.
