I recently received and swapped out the keyboard on my Pocket and now the button for the scrolling (second to the right of the trackball) is no longer working. It must not be mapped to trigger scrolling. When I press the key in the terminal, it pastes the contents of my clipboard.
Is there a way to remap the key to trigger scrolling with the trackball?
The keyboard firmware update changes the key layout. Should be from right to left, right click, scrolling, left click, and then finally paste or something. Not sure really. This is different from the firmware that shipped with the KB.
Just tested all of the keys. Probably should have done that from the beginning. 
From right to left: paste, left click, scroll, right click.
