I think there's a new Tex/Latex StackExchange site these days... may be a better place to ask – Nov 25 '10 at 19:54

2See the answer to http://tex.stackexchange.com/questions/8851/how-can-i-highlight-some-lines-from-source-code , it should apply to this question, too. – Jan Hlavacek Feb 01 '11 at 14:04

Given that this is an old question and the context is not overly clear, I'm minded to close this as a duplicate of the question that Jan links to. Any objections? – Andrew Stacey Feb 03 '11 at 11:49

@Andrew: agreed. – Juan A. Navarro Feb 03 '11 at 13:03

I'm not sure that you can. The listings package provides its own macros for emphasising words in source code listings. For example, by default it emphasises language keywords. You can alter or add to the words that the pakcage emphasises. The following snippet, from the listings documentation,
\lstset{emph={square,root},emphstyle=\underbar}
will cause listings to set the words square and root with an underline.

While hard to discern from the way the question was phrased, I believe the OP wanted to format text inside a TeX code listing made with the
listingspackage. And of course, when he/she tried to do that, the commands appeared as they are, and no formatting took place. – Martin Tapankov Feb 01 '11 at 14:45
