Forums → Programming Forum → Code which about pressing button

Th players can press "W A S & D" to control the movement of the chacters during the game. But, what is the code of this?
Moreover, I don't know what the name of the button is.
For ex. "space" button is :
if (keyisDown(Key(space)){
_root.gotoandplay(2);
}

But , how about other?(Key"A","B","c"...)
If I write this:
if (keyisDown(Key(A)){
_root.gotoandplay(2);
}
It didn't work when I press button "A"?!
Can someone tell me about this???
