Suspect you'll get a far more detailed answer in Questions than in here - there are at least one or two Concorde pilots (ex Concorde pilots?) who read that forum. But, as far as I know, the control surfaces at the back of the wings are "elevons" - combination elevators and ailerons. Move the controls on each side in the same direction for pitch control, or in oposite direction for roll control. Quite happy to be corrected on this one, though.
