Merry Christmas.

rx-51.txt

I presume you don't need to be told to backup the relevant file. This is the original file, just copied over with the name "rx-51.txt" since talk.maemo.org doesn't like files without an extension as uploads. So there's no metadata that things like notepad/wordpad or whatever leave in .txt files.

So, just mv/cp to /usr/share/X11/xkb/symbols/nokia_vndr/rx-51

Edit - "original file" is bad wording choice. I mean, it's my current file, but it's the exact copy of it, not a copy-paste of the text in it.
