Event:KeyboardEvent & keyCode problem

1

So I am fairly new to AS3. I have an image moving round the screen so far using arrow keys and that works just fine.

The problem I have is registering the ‘p’ key hit. At the moment it is only registering when I use ‘shift’ along with ‘p’. But I want to be just able to press ‘p’ on its own.

Heres a snippet of my code:

function KeyUp(event:KeyboardEvent){
     if(event.keyCode == 80){ 
          key_p = false;
     }
}
 
function KeyDown(event:KeyboardEvent){
     if(event.keyCode == 80){ 
          key_p = true;
     }
}

This moves an image on the screen at a diagonal so I can visualy see if ‘p’ is being pressed.

if(key_p == true){
     hero.x += 2;
     hero.y += 2;
}

Thanks in advance.
