1. A tool for selective release of at least one object from a subterranean location to an adjacent location where said object lands to perform a borehole operation, comprising: an outer housing with opposed connections for attachment to a tubular string and disposition at a predetermined subterranean location; a mandrel having a passage therethrough and movably mounted with respect to said outer housing, said mandrel having spaced wall openings defining a bypass flow passage around at least one selectively retained object that seals said passage; said object initially supported in said passage and selectively released to travel to the adjacent location; said mandrel extending outside said housing through said tubular string for remote actuation of said mandrel to release said object to move through said passage and to selectively close one of said spaced wall openings to facilitate use of applied pressure to remove said object from said passage.
