title: Opera preventDefault() on keydown event
body: <p>I'm trying to embed some keybindings in my webapp, and I'm having hard times with Opera. I have this code:</p>
  
  <pre><code>window.onkeydown = function(e){
    var key = e.keyCode ? e.keyCode : e.charCode ? e.charCode : false;
    if (e.ctrlKey &amp;&amp; key === 84) {
      alert("foo");
      e.preventDefault();
      // return false;
    }
  }
  </code></pre>
  
  <p>It works like a charm in Firefox and Chrome, but Opera still opens new tab. Same happens with <code>return false;</code>.</p>
  
  <p>My info: <code>Opera/9.80 (X11; Linux i686; U; en) Presto/2.7.62 Version/11.00</code></p>
