I had earlier asked a question about how to have the textmate editor highlight the footnotes in my latex document. Link: http://www.nabble.com/Highlighting-in-Textmate---Latex-to20379168.html#a2037...

I had two very good responses to that question about how to find the scope and how to modify the preferences. For footnotes, the scope was meta.footnote.latex

Now I am using a package called "changes" in latex, which defines commands like \added, \deleted and so on for tracking changes. I want to highlight anything that appears in the braces in \added{}. Using the method suggested in the above post I found the scope as meta.group.braces.tex. But this scope is common to many other pair of braces (for example, subscripts, superscripts, \vspace{} etc.) and it highlights all those too. How can I have the editor just highlight something that appears between \added{}.

Thanks very much.
