Actionscript 2 Blackjack Game

I would like to create a 'just for fun' blackjack game in Flash using Actionscript 2. It should mimic this one: [login to view URL] Note that this one is able to scale fullscreen with no problems (vector graphics), it has sounds, etc. The only thing I want to do differently is have the ability to play the game using only the keyboard. So it would mean adding the necessary onPress handlers to enable navigation using up,down,left,right on the keyboard. When this is finished I should be able to easily open the provided .fla file and make simple changes such as changing the graphic on the table or on the face of the cards.
