Using ActionMap for HotKey mapping

Anyone used ActionMap, InputMap and KeyStroke classes to map key strokes to gui actions and passed the exam??! I am not sure if Sun considers this design is something that a junior programmer can't understand.
As always, your opinions are greatly appreciated.

Hmm. Ive never used it. Not like you really need to though. Its not like the GUI is complex(at least mine isn't). Two whole buttons on mine.

I suppose it would be a good thing to know though

The code is not that hard. You just have to get the details ironed out. Below is the method defined in my search panel class, I use for KeyStroke mapping:

In my search panel controller, the inner class extends AbstractAction instead of implementing ActionInterface.

Mark is going to definitely say it is a overkill. Is it true Mark? I don't want to fail...please...

Let's see I had 4 ActionListeners, 1 Focus Listener, and 1 ListSelectionListener
The FocusListener is just like your ActionMap and only took me 1 line of code that is using the basic Action/Listener pattern in java which every Junior programmer learns in the beginning.

But yours is not overkill. , and I mean that.
