Earth-boring tools may have a body, a cutting element attached to the body at a first location, and a formation-engaging structure attached to the body at a second location. The formation-engaging structure may be movable during a drilling operation between a first position and a second position. In the first position, the formation-engaging structure may be located rotationally behind the cutting element at a first radial distance from a longitudinal axis of the body at which the cutting element will at least initially shield the formation-engaging structure from engaging a formation. In the second position, the formation-engaging structure may be located at a different second radial distance from the longitudinal axis of the body at which the formation-engaging structure will engage a formation.

A directional drilling apparatus include a first cutter that substantially cuts a wellbore bottom along a first axis and a second cutter that cuts the wellbore bottom along a second axis different from the first axis. The second cutter may extend an adjustable amount out of the first cutter. The pilot string may connect the second cutter to the first cutter.
