1. A method of implementing auto-guidance, the method comprising: in response to a first electromechanical switch input from a user using one of three or less electromechanical switches without using any graphical user interface display while a mobile machine is at a first point, setting by the auto-guidance system the first point for auto-guidance of the mobile machine; in response to a second electromechanical switch input from the user using one of the three or less electromechanical switches without using any graphical user interface display after movement of the mobile machine from the first point to a second point, setting by the auto-guidance system the second point for auto-guidance of the mobile machine; activating, by the auto-guidance system, auto-guidance of the mobile machine; and automatically guiding, by the auto-guidance system, the mobile machine along a path defined by the first point and the second point; wherein the setting of the first point, the setting of the second point, and the activating are performed by one or more hardware processors.
