I'd say that the rudder controls yaw, period.

You can change heading using the rudder. I've done it (hah, especially
a lot as a student trying to practice power on stalls), and it stands
to reason considering the force vectors acting on a fuselage that is
yawed into the relative wind. I've never tried to do what Bertie
describes though. But I will next time I'm up.

Nevertheless I follow the school that says the elevator is really the
main turn control (Langewiesche, Stowell, and many others).
