title: Highlight all references to X?
body: <p>The Eclipse IDE has a neat little feature that I really miss in Visual Studio.</p>
  
  <p>If I place the cursor on a variable or method name, the IDE will automatically highlight all references to it in the current document within the relevant scope.</p>
  
  <p>I can't seem to find an option to turn on similar behaviour in VS2008 or Resharper 4.  I know VS has a Find Usages function, but I'd like to do it automatically on the fly.</p>
  
  <p>Does anyone know of a free addin which will add this functionality?</p>
