Is it possible to bypass keystroke to browser?

Question

I have a page with java applet. I want users to be able to press F11 to maximize their browser. Unfortunately, when focus is on applet, F11 doesn't work (Java handles it and doesn't pass it to browser). Is there a way to make F11 work? Actually, I don't need any input from my keyboard in applet, so bypassing all keyboard input to browser will be fine too.
Thanks,
Victor

Two notes:
1) If you had added Dukes stars to the thread, I might have noticed it when you first posted it.
2) If you appreciate this solution and wish to express your thanks, the best way to do it is to (log-in, ) add some Dukes to the thread, and assign them.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
Intercepts the F-11 (function key 11) to toggle 'full-screen' mode.
A trusted applet would appear without the 'Java Applet Window' banner.
public class FullScreenApplet extends JApplet implements KeyListener {
  JWindow fsw;
  boolean fullscreen = false;
  public void init(){
    JPanel p = new JPanel(new BorderLayout(4,4));
    // add the KeyListener to any focusable components..
    JTree tree = new JTree();
    tree.addKeyListener(this);
    p.add( new JScrollPane(tree), BorderLayout.WEST );
    JTextArea textArea = new JTextArea();
    textArea.addKeyListener(this);
    p.add( new JScrollPane(textArea), BorderLayout.CENTER );
    p.add( new JLabel("Message.."), BorderLayout.SOUTH );
    // make the panel focusable and also add the listener to it,
    // just in case there are no other focusable elements.
    p.setFocusable(true);
    p.addKeyListener(this);
    getContentPane().add(p);
  JWindow getFullScreenWindow() {
    if (fsw==null) {
      Container c = getContentPane();
      while (c.getParent()!=null) {
        c = c.getParent();
      Window w = (Window)c;
      fsw = new JWindow(w);
      fsw.setSize(
        Toolkit.getDefaultToolkit().getScreenSize());
    return fsw;
  public void toggleFullScreen() {
    JWindow w = getFullScreenWindow();
    if ( fullscreen ) {
      w.setVisible(false);
      Container c = w.getContentPane();
      this.setContentPane(c);
      this.validate();
      fullscreen = false;
    } else {
      Container c = this.getContentPane();
      w.setContentPane(c);
      w.validate();
      w.setVisible(true);
      fullscreen = true;
  public void keyReleased(KeyEvent ke) {}
  public void keyPressed(KeyEvent ke) {
    if (ke.getKeyCode()==KeyEvent.VK_F11) {
      toggleFullScreen();
      Component c = (Component)ke.getSource();
      c.requestFocus();
  public void keyTyped(KeyEvent ke) {}
}
