Using WinSCP, navigate to root/usr/local/share/xbmc/system/keymaps/remote.xml. Copy the remote.xml file to your local machine. Edit the remote.xml file so that the coloured buttons under the global section match your requirements. Mine is shown right. Copy the remote.xml file back to /home/xbian/.xbmc/userdata/keymaps then reboot your Pi.

I recently configured a Raspberry Pi for a friend using Xbian and a Sony 46" LCD. It worked flawlessly with CEC support although there were a few commands that the Sony TV (remote) would not pass through the HDMI cable to the Pi.As such, I had noorbutton which are both rather useful. After spending a few hours searching about, I managed to resolve it by remapping the coloured buttons below the D-Pad to perform the following:Red = Context MenuBlue = InfoYellow = Update video libraryGreen = Clean video libraryYou can only remap buttons that are supported by your TV remote. i.e. If you push a button on your TV remote and your TV performs a TV function (in my case the number buttons switched back to TV and that channel) or the TV displays a message saying "Unsupported" or something similar, there is nothing you can do with that button. Those buttons are not being sent via CEC back to the Pi over HDMI.The IP address of your Pi.WinSCP or a similar tool to SCP into your Xbian instance.You should now have access to the Context menu with the Red button and Info (for video information etc.) on the Green button.
