I still do not understand this stupidity, pressing *one* key cause 
emitting two keys to OS and then OS needs to handle combinations of keys 
and acts on it correctly.... (like windows manager)

Is there some way to disable this insane nonsense activity of BIOS, 
firmware or whatever it is doing in HW to send *one* key scancode when 
pressing *one* key?
