arrow key movement and gravity as2-->as3

[medfoe]

I'm trying to make the transition between actionscript 2 and 3.

I noticed that the following code makes the object move over 10 pixels on the key-press, then waits a second to make it move more:

stage.addEventListener(KeyboardEvent.KEY_DOWN, move);

function move(e:KeyboardEvent):void {
if(e.keyCode == 37) {
object.x -= 10
}
}

I want the constant movement to start immediately.

Moreover, the following code is only executed once, instead of every frame like in actionscript 2:

this.y += 10

I want it to be executed every frame.

Anyone know how to make it do those two things?
