Okay, I gotcha now.

I don't own a N810 so I wasn't quite sure all of what you were saying.

Can't you simply remap that rocker button from the keyboard to another hardware button like the center D-Pad?

Maybe take a look at this thread.

You can find out what the code is by installing Xev, which can be found here along with Xmodmap.

Best of luck.
