My current xkb setup is as follows:
$ setxkbmap -query rules: evdev model: pc104 layout: us,cz(qwerty) options: lv3:ralt_switch_multikey,grp:lalt_lshift_toggle
When in the
us layout, a combination of right shift and right alt works as the compose key (also called multi key). When in the
cz(qwerty) layout it doesn't do anything.
I also tried to switch to a much better layout for me as a czech/english writing programmer and I was told about
us(cz_sk_de). Unfortunately compose key doesn't work for that layout either.
I suspect it is related to the number of levels used in a keyboard layout as both failing layouts offer additional characters using right alt. What is the best way around?
