For anyone else considering this, and with limited/no Linux experience, here are some tips from my experience.
Firstly, forget about PuTTY and other SSH utilities to log on to your Pi, unless you are already Linux-friendly. If you have Windows, install WinSCP, which allows you to log onto RuneAudio and exchange files with your PC, through a user-friendly interface. Default userID/pwd for Rune are root/rune. Obviously you need to know the IP address of your Pi, and it helps if you have setup your router so that the Pi keeps the same IP.
Secondly, set WinSCP to show hidden files, because the one we want has a name which starts with a ".", so it is hidden.
Thirdly, when you copy the file (.xbindkeysrc) to your PC, don't start editing it with Notepad or Wordpad, since there is something about the end-of-line characters in Linux/Unix which is different to Windows. When you send it back to the Pi, xbindkeys won't read it properly. I use the PFE editor to avoid this, which has a default unix-style end-of-line.
Finally, here is a cleaned-up version of the command file which I used after some experimentation. It uses the skip and back keys for track changes and the left and right arrow cursor keys for seeking back or forward by 10s. Up and down are redundant. I couldn't find a way to stop/start (apart from the <enter> key for pause/play), or mute. I gave up experimenting since you have to reboot the Pi every time you load a new command file. I couldn't find any definition of keys which included the codes used by the OP. I have commented out the commands which do not work, to avoid trying them again.

Would be interesting to know where those last few key codes come from, like "m:0x0 + c:113", or if anyone got stop/start or mute to work. Stop/start would resume at the beginning of the present track in my logic (or maybe at the beginning of the playlist?). Also it would be good to be able to restart the current track, without going back one and then forward one.
