title: In Visual Studio, how do I debug a project without building it
body: <p>This is for Visual Studio 2008.</p>
  
  <p>I have <code>Tools|Projects and Solutions|Build and Run|On Run, when projects are out of date</code> set to <code>Always build</code> because that is what I usually want.  However, there are some times (when I am examining historic versions in version control) where I want to skip the build process.  Is there a magic keystroke that will override the build step for exactly one debugging session so I don't have to change the setting and change it back?</p>
