When I refer to a book which explains interrupts it tells me:
Service 10H: Extended Keyboard Read
Service 11H: Get Extended Keystroke Status
Service 12H: Get Extended Shift Status
 
These functions are the equivalents of services 0, 1 and 2 respectively.
They return additional info available on 101 key (AT style) keyboards,
e.g. F11, F12, left vs. right Alt and Ctrl.  The book is The *New*
