Hi there.

I recently bought two bluetooth nunchuck-like controllers.
You hold it in one hand and it has a swivel X-Y axis thingy for your thumb.

As a test I paired them with my laptop.
I discovered that buttons C and D change the volume and somehow Amarok 
interprets some button presses as next track, although that doesn't work 
consistently.

I started looking for programs to do the button mapping but I couldn't 
find one that worked with this controller.

My question is, where are these mappings stored in Trinity?
