title: Replace keyCode in IE 11
body: <p>We use this code for simulating <kbd>Tab</kbd> key with <kbd>Enter</kbd> key:</p>
  
  <pre><code>function EnterTab() {
      if (event.keyCode == 13) event.keyCode = 9;
      return false;
  }
  </code></pre>
  
  <p>But in IE 11 <code>keyCode</code> is <strong>readonly</strong> and this code does not work. How I can solve this problem that my code run in IE 11?</p>
