Sorry for the noise, but as I wrote in my first reply, xmodmap does not have
any desired effect.
With my tests, all I can change is normal and shifted behaviour. So only the
first two columns of a
keycode definition has an effect in the keysym output. I assume that is because
evdev processes the codes in some other way. For example Alt + 2 gives
(twosuperior) in my terminal, whatever I configure with xmodmap.
xkbcomp -xkb :0 /tmp/xkbfile
shows
key <AE02> {
type= "FOUR_LEVEL",
symbols[Group1]= [ 2, quotedbl, 3,
oneeighth ]
};
after some xmodmap experiments, but still Alt+2 give and Alt+Shift+2 gives ¢
(cent).
Conclusion: Whatever I do, there is another layer of processing that isn't
affected by xmodmap or xkbcomp at all.
