keyboard key command for play after a stop

[jazzbluejazz]

I made a full screen presentation by Flash and i put some Stop at keyframes during the movie.
How can I resume in play (after the stop) the movie using one only keyboard key instead of CTRL + Enter ?
I would specify that I'm using Flash 5 and Projector as a export mode

a friend told me to put this script in a keyframe in a new layer

onEnterFrame = function(){
if (Key.isDown(Key.RIGHT) {
this.play();
}

but it doesn't work ?
any idea to suggest me to solve this problem?

Thanks in advance
