In the comments to my previous post about remapping keys on the keyboard of my N810 there was a mention of editing the X server keyboard mapping file at /usr/share/X11/xkb/symbols/nokia_vndr/rx-44, which I assumed was a pretty nasty hack. But Daniel Stone, who does the X server development for Maemo, said that it wasn’t a hack at all. xmodmap is the hack.
Yesterday I was starting to get annoyed at having to manually load the mapping at every reboot (cause I have to reboot frequently to get GPS working again, groan), so I swapped techniques. The format of the file is pretty easy to understand, use “bar” where you want to put the pipe symbol and “Tab” where you want to put tab. And while I was in there digging at it I changed my mappings to, I made Fn-space the tab key instead of using semicolon. Just seems like a more intuitive setup.
