I need to change the language from keyboard for example : Alt+Shift or similar.
I have already installed all language.
Switching keyboard language by Right Alt+Shift does not work. Alt+Shift doesn't change language. I can't type my language even with ru, bg, en input switched on in language bar.
The language is bar missing.
Edit from comments:
I have UK and Bulgarian keyboards enabled, I have enabled Alt+Shift as the primary short cut and Ctrl+Alt+K as the alternate in my settings. the current selected keyboard layout is not indicated in the systray and I cannot find a plasmoid for it either. If I hit Alt+Shift nothing happens. If I hit Ctrl+At+K a rounded grey square with icon of a globe and letters UK (representing UK layout) are displayed on screen, if I hit the combination again, it again shows uk and does not switch the layout.
