title: Visual Studio 2010 Themes : Properties Reference
body: <p>I would like to change the color of the vertical line of collapse/expand code. Cannot manage to find the right property in the "<code>Customize Colors</code>" Dialog in the Themes Menu.</p>
  
  <p>I did not manage to find anywhere <strong>a decent, exhaustive, and ideally visual reference for the theme properties</strong>. I usually end-up trying blindly and changing obscurely named properties on and on, until I finally stumble on the right property by chance, or give up.</p>
  
  <p>this May also be hidden somewhere in <code>Environment&gt;Fonts</code> and Colors...</p>
  
  <p>Any Ideas ?</p>
