Claim 12:
13. A method of creating axial movement of an inner sliding sleeve member on a tool located in a well, the inner sliding sleeve member of the tool including a first profile on an inner surface, comprising the steps:
(a) running apparatus on a work string into the tool, the apparatus comprising:
an inner mandrel having a coupling at a first end to connect to the work string and an end cap with an upper facing lip at an opposing end, the inner mandrel including first and second spaced apart stops located there upon;
a first sleeve located around the inner mandrel and moveable relative thereto, the first sleeve comprising a key carrier in which is located a plurality of keys biased radially outwards from the inner mandrel, each key having a second profile on an outer surface;

(b) mating the first profile on the inner surface of the inner sliding sleeve member with the second profile of each key to engage the inner sliding sleeve member with the apparatus;
(c) applying a force on the upper end of the inner mandrel, the force being transmitted to and axially moving the inner sliding sleeve member; and
(d) moving the upper facing lip over the plurality of keys to retract the keys and release the inner sliding sleeve member from the apparatus.
