need to show code line numbers so I can use error list more efficiently

I am convering existing html 4 pages to Xhtml and using visual web express 10 for the first time.  I have found how to show the error list but can not seem to find how to make the program show the line numbers in my code so I can find the errors quickly. 
Help if you can.

Look around in  the Tools menus.  Particularly Settings and Optiions.  Check boxes that give you more choices.  Find TextEditor–>All Languages–>Line Numbers.

Thanks for answering… I stumbled on to my solution… just double click the error message and it highlights the code that is wrong.  Goes right to the offending line.  I should have known it would be something simple like that.
