This is a shortcut for switching layouts which is handled by KDE. It does not support modifier-only shortcuts and also may not work in some situations (e. g. if popup is active or from screensaver).
Dit is in fluchtoets om te wikseljen fan yndieling hokker hannele wurdt troch KDE. It stipet net de modifikaasjetoets as fluchtoets en kin ek wolles net wurkje yn oare situaasjes (bgl. in aktive popup of in skermbefeiliging.)
