Xorg. Настройка клавиатуры + compose key

Мои стандартные настройки клавиатуры для нового стиля конфигурации Xorg.

/etc/X11/xorg.conf.d/10-keyboard.conf

Section "InputClass"
    Identifier "Keyboard Defaults"
    MatchIsKeyboard "yes"
    Option "XkbLayout" "us,ru(winkeys)"
    Option "XkbOptions" "grp:caps_toggle,grp_led:scroll,compose:menu"
EndSection

Для ввода специальных (и не очень) символов непосредственно с клавиатуры в Linux можно настроить так называемую compose key. Набор производится следующим оразом: нажимается и отпускается compose key (из конфига выше видно, что у меня это клавиша «Menu»), затем вводятся остальные символы из комбинации.
«Раскладка» записывается в файл ~/.XCompose
