title: A shortcut that works on all OS's on all Browsers?
body: <p>For my javascript app on <a href="https://teletext.io" rel="nofollow">https://teletext.io</a> we need a shortcut to launch the editor. The idea is to include a javascript on your own website and pressing a key combination like ALT+SHIFT+T will enable editing mode. However a combination like that doesn't work in all browsers (on all OS's).</p>
  
  <p>For example:</p>
  
  <pre><code>function addKeyboardShortcut() {
    window.onkeyup = function(event) {
      if (keyid === 84 &amp;&amp; event.altKey &amp;&amp; event.shiftKey) {
        txt.loadAdmin();
      }
    }
  }
  </code></pre>
  
  <p>How to pick a shortcut that does not interfere with the default browser shortcuts, what is the safest option? </p>
  
  <p>Edit: simplified code as Alexey pointed out.</p>
