OSBYTE &76

OSBYTE &76 (118) - Reflect keyboard status in LEDs

   This calls KEYV to update the keyboard LEDs. If the keyboard
   status byte (CAPs lock etc...) is written to with OSBYTE 202 then
   the LEDs should be updated by using this call. Under normal
   circumstances the LEDs look after themselves.
   
   On exit:  X.b7=CTRL key pressed
   Note that other documentation state that this call returns the state
   of the SHIFT key. This is incorrect.
