title: Disable Shortkeys when Ctrl or Shift clicked
body: <p>I am trying to disable all shortkeys when certain keys (<kbd>Ctrl</kbd>/<kbd>Shift</kbd>) are clicked.</p>
  
  <p>This is my quick snippet:</p>
  
  <pre><code>$(document).keyup(function(b) {     
  
      if (b.keyCode == 16) {return false;}
      if (b.keyCode == 17) {return false;}
  
      $("body").append(b.keyCode + " ");
  
  
  });
  </code></pre>
  
  <p>​When ever you click <kbd><strong>Shift</strong></kbd> or <kbd><strong>Click</strong></kbd>, the keyCode number <strong>is not</strong> printed but if you click <kbd><strong>Shift</kbd> + <kbd>Any Letter</strong></kbd>, the keyCode of the letter <strong>is</strong> printed.</p>
