Custom draggable area in HTML/HS based AIR app?

For my second AIR app, I've decided to try using JS as I'm more comfortable with that than I am with Actionscript 3. I'm having trouble figuring out how to define a specific div to be the draggable area for my app. It's fairly straightforward with Actionscript. Define an event listener in the init method   // initialize the draggable area for the title bar   navBar.addEventListener(MouseEvent.MOUSE_DOWN,startMove); The startMove method:   // this method triggers the navbar drag functionality   private function startMove(event:MouseEvent):void{     stage.nativeWindow.startMove();   } How am I supposed to trigger this functionality? Also, is there a good, comprehensive reference for Javascript developers who want to build AIR apps?
