The leading edge slats on modern aircraft are all coupled into the other controls. For example during a high speed flyby the slats, flaps and elevator are all set level (or near to) but during a pitch up maneuver the flaps and slats lower as the elevator angles for the pitch control. A negative pitch maneuver would reverse this with the slats and flaps going up above the "flat" position to alter the camber for higher inverted lift. Similarly I believe you'll find that the ailerons are also coupled into the slats so that when the aileron goes down the slat does as well (very slightly) and conversly the up traveling aileron is linked to that slat going up slightly as well.

On the angled fins of the F18 the rudders actuallly turn in slightly during pitch up and out slightly during pitch down to minimize drag relating to how the air flows past them.

Ain't computers wonderful?
