Remapping RaspBMC Remote Keybindings

I've updated my HTPC to be a Raspberry Pi that uses RaspBMC as the OS. The really hard part was integrating my existing RAID with the device (over USB) to serve up my media; that's a subject for another post.

Something that didn't quite work out of the RaspBMC box (and to be fair A LOT did work) was the Context Menu for XBMC. I like to call it the "right click" option if I was using a mouse. This was because my remote didn't have the default button that XBMC was expecting. As mentioned in a previous post I have a generic RC6 IR receiver that I had used the mceusb2 kernel driver. Looking at the remote config file for XBMC (/opt/xbmc-bcm/xbmc-bin/share/xbmc/system/keymaps/remote.xml) the ContextMenu is mapped to the <title> key. Looking in the LIRC config file for XBMC (/opt/xbmc-bcm/xbmc-bin/share/xbmc/system/Lircmap.xml) for a mceusb remote the "title" is mapped to the "Guide" key. Looking on my trusty remote diagram there was a Guide button, but why didn't it bring up the context menu?

Turns out that RaspBMC was using a different remote config in Lircmap.xml Using irw to see the remote codes I get:

16d 0 KEY_EPG devinput
16d 0 KEY_EPG_UP devinput

Searching Lircmap.xml for devinput I got a different <remote> profile, with no mapping for <title> So I added:

<title>KEY_EPG</title>

and the Context Menu is displayed.

Handy little util irw for figuring out remote config.
