ABSTRACT:
A downhole tool includes, a tubular, a tooth profile on the tubular, at least one first actuatable latch complementary to the tooth profile and at least one second actuatable latch complementary to the tooth profile. The at least one second actuatable latch prevents movement of the tubular when actuated. Additionally, at least one actuator is in operable communication with the at least one first actuatable latch such that actuation of the at least one actuator while the at least one first actuatable latch is actuated and the at least one second actuatable latch is nonactuated causes movement of the tubular.
