The MC9190  53Key - Keypad have only printed blue lablels from F1 to F10. Can I  use the F12 key using  "Shift"+"2"  just like a 53key -VT Emulation Keypad ? Is it correct to say that the only difference between the  53-Key only and  53key-VT Emulation Keypad  are the additional  yellow and green labels but it is just the same hw?
