title: Javascript: addEventListener with onkeydown doesn't seem to work
body: <p>If you replace "onkeydown" with "click", it reacts, at least.</p>
  
  <pre><code>&lt;input id="yourinput" type="text" /&gt;
  
  &lt;script type="text/javascript"&gt;
  document.getElementById("yourinput").addEventListener("onkeydown", keyDownTextField, false);
  
  function keyDownTextField() {
  alert("functional");    
  if(keycode==13) {
          alert("You hit the enter key.");
      }
      else{
          alert("Oh no you didn't.");
      }
  }
  &lt;/script&gt;
  </code></pre>
