title: How can I change my Visual Studio 2010 Help (F1) from local to online?
body: <p>The first time I pressed F1 in Visual Studio 2010, I mistakenly chose to use local help files (which I don't have) rather than online.</p>
  
  <p>Now, whenever I press F1 in VS2010, The Microsoft Help Viewer 1.1 launches with nothing in it.</p>
  
  <p><strong>How do I change the F1 behaviour to online help?</strong></p>
  
  <p>Note: There appear to be Help settings in Tools > Options for <a href="http://msdn.microsoft.com/en-us/library/4zzt41xa%28v=VS.90%29.aspx" rel="noreferrer">VS2008</a> and <a href="http://msdn.microsoft.com/en-us/library/4zzt41xa%28v=VS.80%29.aspx" rel="noreferrer">VS2005</a>, but none for <a href="http://msdn.microsoft.com/en-us/library/kct8y8f0.aspx" rel="noreferrer">VS2010</a>?</p>
