title: keydown in flex Flex
body: <p>I have an small application in flex in which I have defined 2 canvases. On one of them I added controls and the other one is used to draw something and no controls are added:</p>
  
  <pre><code>&lt;mx:Canvas x="0" y="80" width="100%" height="520%" id="Canvas1"/&gt;
  &lt;mx:Canvas x="0" y="0" width="100%" height="80" id="Canvas2"/&gt;
  </code></pre>
  
  <p>I add an keydown event handled to the application but it is triggered only after I click with the mouse on the first Canvas(the one where controls have been added). Otherwise the event is not triggered when keys are presses.</p>
  
  <p>I've tried several things: to set focus on the second canvas, to add the keydown handler to the application(this),stage, canvas... Unfortunately I didn't find a solution to trigger keydown no matter where the focus is.</p>
