I was not thinking of the yoke or pedals as controls. I was thinking
more buttons and knobs. If they count ... then it's the elevator.

Nah. You should be able to fly using ailerons and trim without the
elevator. I had one instructor have me land doing just that. The AOPA
even put out a video on doing it.

When I was getting my float rating the instructor had me take off
using just trim and rudder
