title: Play timeline in reverse when holding a button
body: <p>Basically i'm trying to create two buttons. They both call actions while the user has their cursor held on them (rather than onClick or anything like that). </p>
  
  <p>The first one plays the timeline, which works great.</p>
  
  <p>The second one I need it to play the timeline in reverse while the user is holding down the button, how do I do that? Code below:</p>
  
  <pre><code>import flash.events.MouseEvent; 
  
  
  // Play timeline forwards on click //
  function onButtonClick( event:MouseEvent ):void 
      { 
          play();
      }
  RotateRight.addEventListener(MouseEvent.MOUSE_DOWN, onButtonClick);
  
  // Stop timeline forwards on release //
  function onButtonClick2( event:MouseEvent ):void 
      { 
          stop();
      } 
  RotateRight.addEventListener(MouseEvent.MOUSE_UP, onButtonClick2);
  
  
  
  // Play timeline in reverse on click //
  function onButtonClick3( event:MouseEvent ):void 
      { 
          // PLAY IN REVERSE?
      }
  
  
  RotateLeft.addEventListener(MouseEvent.MOUSE_DOWN, onButtonClick3);
  
  // Stop timeline in reverse on release //
  function onButtonClick4( event:MouseEvent ):void 
      { 
          stop();
      } 
  RotateLeft.addEventListener(MouseEvent.MOUSE_UP, onButtonClick4);
  </code></pre>
  
  <p>Any help is most appreciated :)</p>
