I am wanting to make the Add key on the keyboard to be used as a Tab. I
included the following code
this.addKeyListener(new java.awt.event.KeyAdapter() {
      public void keyTyped(KeyEvent e) {
              }
      public void keyPressed(KeyEvent e) {
             int key = e.getKeyCode();
                     if (key == KeyEvent.VK_ADD){
                         getFocusOwner().transferFocus();
             }
      }
    });

This works kind of okay but the problem I am getting is that a Plus sign

is also put into my text fields. Is there a way I could completely
disable that Add key and map it to a Tab key. Can this be done on the
OS. I am using WINNT.

Thanks
