Mouse Views:
Bomber Gunner External View : Exclusively use mouse
Fighter Internal View (non-combat): In co-ordination with keypad views to assist in scanning for targets, also verifying gauges/indicators (my wheels are still down!

)
Ground Vehicles: 60% of the time for course view changes; switch to joystick for fine tuning range.
All Manned guns used a combination of joystick and mouse views.
