title: Trying to get the char code of ENTER key
body: <p>I have this this code:</p>
  
  <pre><code>newSymbolTextBox.addKeyPressHandler(new KeyPressHandler() {
    public void onKeyPress(KeyPressEvent event) {
        System.out.println("foo =" + KeyCodes.KEY_ENTER);
    System.out.println("bar =" + event.getCharCode());
    }
  });
  </code></pre>
  
  <p>When I press ENTER I get this output:</p>
  
  <pre><code>foo =13
  bar =
  </code></pre>
  
  <p>I expected a value after <code>bar =</code>. Any idea?</p>
