the sim document (
http://www.rockbox.org/twiki/bin/view/Main/UiSimulator)
doesn't seem to list the keypap for the ipod.
the cursor keys sometimes map to the four wheel buttons on the ipod, except that
the volume is controlled by the up/down buttons like on the gigabeat.
What is the key map for the ipods? It seems to change depending on what screen
you are in. I can't find the scroll wheel 'keys' or the hold switch. Select is sometimes
the space bar. (I got stuck in the simulator with the rockblox plugin, couldn't
rotate the pieces or quit the game).
At least enough worked so I could play around with WPS changes.
