I should have been a little more clear. I have an N810, and the file seems to be a little different.

When I go to usr/bin/wiicontrol and edit it using vi, I can see that instead of:
[Left] # dpad left

it's something like:
A: [a m]

but some entries have a "k" like:
A: [k space]

and I don't quite understand the difference.

Also, programming the gryo is kind of strange. Am I correct when I assume tilting the controller forward (with the front edge going down) is gyro up and backward (with the back edge going down) is gyro down?
I want to reprogram the gyro to work as the arrow keys do in the sideways orientation of the controller.
