title: Visual Studio hot keys change occasionally, specifically F6 vs Ctrl-Shift-B for building. WHY?
body: <p>I always press <kbd>F6</kbd> to build my project.  Suddenly some of my Visual Studio instances are wanting me to use <kbd>Ctrl</kbd>-<kbd>Shift</kbd>-<kbd>B</kbd>.  It's not keyboard related - the actual text of the menu option changes from "<kbd>F6</kbd>" to "<kbd>Ctrl</kbd>-<kbd>Shift</kbd>-<kbd>B</kbd>".</p>
  
  <p>Any answers as to how to fix, and <strong>what causes this</strong>?</p>
