When refuelling in a Tornado there is little need to move fuel panel switches whilst in contact, but even on those rare occasions, it's not a big deal to look in momentarily to find the correct switch. The formation flying required once in contact is pretty forgiving (with the notable exception of the boom-drogue adapter, which can be a pig). A much less exciting but more challenging proposition is moving switches or tuning navaids during a formation instrument approach in poor weather!
