title: Strange Arrow in Visual Studio Gutter Window
body: <p>What does the following <strong>arrow icon</strong> mean in the Visual Studio 2012 <em>gutter window</em>?  I've never seen it before.</p>
  <p>This particular line of code has nothing special about it, nor do I recall doing anything to this line that would cause an arrow to appear.  It's definately attached to this line of code.  Moving the line of code down causes the arrow to follow.</p>
  <p>I have no add-ons installed in Visual Studio.</p>
