Hey BigNester,
In the init() method of your applet, you have to add your class as a keyListener to your applet.
add the following methods:
// register this class as a key listener
public void init() {
addKeyListener(this);
// unregister this class as a key listener
public void destory() {
removeKeyListener(this);
Later,
