Adding &nbsp to AltGr+SP (gsettings way)

Ask Fedora

hello,

i want to ADD to my keyboard’s space key, nonbreakable space on level 3, and thin nonbreakable space on level 4. that is all. i don’t want to change anything and i am quite happy with my layout.

so far i have done this:

mkdir -pv ~/.config/xkb/symbols

and created a custom file with the following contents:

partial alphanumeric_keys
xkb_symbols "spaces" {
    key <SPCE> {
        type[Group1]="FOUR_LEVEL",
        symbols[Group1]= [ space, space, nobreakspace, U202F ]
    };
};

probably that is crap, as it is advised by chatgpt.

than i entered

gsettings set org.gnome.desktop.input-sources sources "[('xkb', 'fr+custom(spaces)')]"

and lost my Alt-Gr. so i had to redo my old config

i am looking for something in the spirit of the following

gsettings set org.gnome.desktop.input-sources xkb-options "['ctrl:nocaps']"

which works across all apps, and survives reboot, or silverblue upgrades.

Looking at gnome-tweaks that looks like it is:
org.gnome.desktop.input-sources xkb-options ['nbsp:level3n']
