OpenElec Keymap Help (PVR)

How do I bind ‘long-press’ select button on my Fire Stick Remote to bring up the ‘Channel List’ rather than the epg when viewing LiveTV (PVR Client)

I also want to change the up/down to volume up/down rather than channel up/down.

I’ve read through the documentation but am very confused,

Any help greatly appreciated.

Thanks,

Dan
