Eqmod + Stellarium + Gamepad

[Proietti]

Dear all,

I am kind of new to more "serious" amateur astronomy. I am learning to use Eqmod + Stellarium. I was able even to configure, and use, the gamepad. However, each software  has its "dialect" . I was not able to figure out the following: In the Eqmod gamepad configuration window what the "Alignment accept", and “Alignment End” and “Alignment Cancel” does / means?

Thanks in advanceFernando
