Really, it’s all quite simple: as soon as you stop pulling your head back, what else can it do apart from go forward? But you certainly won’t get it by making any sort of movement of the head, although I know that’s what a lot of people, including Alexander teachers, try and do. Let me put it another way: you’re already making the movement by pulling the head back and down, or over to the side or any of the other variations that are possible. So, you’ve just got to stop doing that, and the right thing will do itself.
