You can accomplish that by using Unobtrusive JavaScript, library like jQuery.com will do that for you.

 

 

This will affect all link in your document:

    $(document).ready(function() {
       $('a').onclick(function() {
               pageTracker._trackPageview(  $(this).attr("href")  ) ;
        return false;
        });
      
     });

 

 

This will affect only links in the <DIV id="content"> in your document:

    $(document).ready(function() {
       $('#content a').onclick(function() {
               pageTracker._trackPageview(  $(this).attr("href")  ) ;
        return false;
        });
      
     });

Enjoy!
