How to dynamically control understeer/oversteer in AWD?

I have read a few posts discussing under and oversteer in RWD/FWD yada, yada. I don't recall much discussion on controlling under/oversteer in an AWD as you go through a turn. I don't want to open a discussion on which is better. Rather, I would like some insight on how exactly one can effectively make corrections 'on the fly', so to speak, with AWD. For a RWD or FWD car of a given setup (sway bars and what have you), the car will have a bias. Throttle and steering input can be used in the turn to induce/reduce under/oversteer as desired (one hopes). But in AWD - let's assume a 50-50 torque split for the sake of the argument - throttle changes will not be nearly as effective since it will not cause a shift in the front/rear balance of forces.

I have never driven an AWD anywhere close to cornering limits so, tell me, how do you control oversteer, say, in AWD should you hit a patch of gravel in the rear suddenly? Just steer into the slide and get off the throttle?

Or am I way off the mark?
