I'm not sure that this behavior is the best, but did not come up with a more 
convenient. I actively use RDP to administer Windows workstations and servers. 
I need to frequently switch the input language on the PC. It would be nice when 
you click any of these shortcuts, change the language of the virtual keyboard.
