 public abstract void processKeyEvent(Component focusedComponent,
                                      KeyEvent anEvent)

This method is called by JComponents when a key event occurs. JComponent gives key events to the focus manager first, then to key listeners, then to the keyboard UI dispatcher. This method should look at the key event and change the focused component if the key event matches the receiver's focus manager hot keys. For example the default focus manager will change the focus if the key event matches TAB or Shift + TAB. The focus manager should call consume() on anEvent if anEvent has been processed. focusedComponent is the component that currently has the focus. Note: FocusManager will receive both KEY_PRESSED and KEY_RELEASED key events. If one event is consumed, the other one should be consumed too.

 public abstract void focusNextComponent(Component aComponent)

 public abstract void focusPreviousComponent(Component aComponent)

Cause the focus manager to set the focus on the previous focusable component You can call this methid to cause the focus manager to focus the previous component
