Normally, I can find solutions by just googling around, but I can't find any decent documentation for xkbdmap except for the grossly inadequate man page.
Perhaps I'm going about this the wrong way. I have a US 105 plain old keyboard that does not have an AltGR key. To the right of the space bar, I have Alt, Windows key, some sort of menu key, and then a Control key.
(what's the point of the Windows key and the Menu key - does anyone actually use those?)
Apparently, some keyboard have another key which is the AltGR key. That with E would give you a Euro symbol for instance, apparently.
Because my keyboard doesn't have this key, I thought to use the xkbdmap command like this:
xkbdmap altgr:rwin
Why does this not work?
