I am not sure witch type is my keyboard. If i seen correctly i got only one (\) backslash key on it (with shift key its (|) "bar").
I 've used exact code for other keys and it works (displaying some text if certain key is pressed) except for some of them. so far i can't get these keys (code is still WIP so i am yet to discover others i need that not work):
\ - backslash
/ - slash
; - semicolon
Thanks for your time.
