title: VS Code for Mac - keyboard shortcut to comment a line no longer works
body: <p>I'm using Visual Studio code on MacOS, version Version 1.25.0 and I'm working with HTML and CSS files. </p>
  
  <p>The keyboard shortcut <strong>"CMD+/"</strong> doesn't comment out the current line. If I open the edit menu and select Toggle Line Comment, that works fine. I checked keyboard shortcuts and the keybinding for that command shows CMD+/. I tried to re-set it, but I couldn't re-add that keyboard shortcut.</p>
  
  <p>Any ideas how to troubleshoot this problem?</p>
