A jigsaw generally includes a housing containing a motor activated by a trigger assembly. A single control member is connected to the housing and configured to be accessible by a user. A reciprocating shaft moves at a reciprocation speed and at a magnitude of orbital motion when the trigger assembly is in a retracted condition. The single control member is operable to be positioned among a plurality of positions. Each of the positions corresponds to a predetermined combination of values of the reciprocation speed and the magnitude of the orbital motion.
