Remapping buttons.

[kryton]

I was using HDMI CEC to control my Edision mini plus from my samsung tv remote and all was working fine.

Ive just bought a new samsung 7 series and now ive found the channel up/down button (zap up/down) no longer works so you cant scroll left/right through the bouquets in the channel selection screen.
All the other buttons work fine.

So i was wondering if it is possable to remap the buttons.
So say for instance i could remap the blue and yellow buttons to do the same function as the channel up/down button (on my edision remote) so i can scroll through the bouquets in the channel selection screen.

Hope that makes sense.
Any help is appreciated.
