title: Keep document open in Visual Studio 2013
body: <p>I noticed in <a href="http://en.wikipedia.org/wiki/Microsoft_Visual_Studio#Visual_Studio_2013" rel="noreferrer">Visual Studio 2013</a> that when you open a document via 'go to definition/f12' the document is only opened temporarily, as soon as you navigate away from the document it closes again.</p>
  
  <p>Now you have to click on the 'keep open' icon in the tab. How do I 'keep open' all those files automatically like in previous versions of Visual Studio?</p>
