Abstract
A multi-function tool is connected to an inner string to selectively align a port or ports in the inner string with ports in the outer string at various locations. The tool is locked from functioning at some locations where a locating collet will not selectively engage with an unlocking profile. In this more the tool will pass through the location unhindered. If an unlock profile is engaged the tool is enabled to be unlocked so that manipulation allows a support mandrel to align with collets that have an external V-shaped profile. Setting down weight allows the supported V-shaped profile on the collets engage a similar profile on the outer tubular to rotate, if needed, and to find support on a V-shaped profile on the surrounding tubular for performance of the borehole operation. Thereafter the locating collet engages a locking profile to disable the tool again.
