Переназначение xkb не работает для некоторых ключей

Я пытаюсь переназначить некоторые ключи с помощью xkb. В приведенном ниже фрагменте я изменил две строки для настройки раскладки клавиатуры. Тот, что для космоса, работает нормально. Но оба из Delete , которые я сопоставил на BKSP , не работают, а BackSpace и AltGr + BKSP = BackSpace работают должным образом.

Я хочу использовать Backspace + Shift как Удалить .

//    key <SPCE> {  [    space      ]   };
// user manipulated next line. this works and has nothing to do with my question.

Прямо сейчас, после проделанных мной манипуляций, нажатие Backspace + Shift дает мне ~ . Я использую X11 и переключаюсь между немецкой и американской раскладкой.
