But I am at a loss how to name those methods, everything I can come up with ("SaveRecordNumber", "MoveBackToRecordNumber") do not sound anything intuitive. Anybody has a bright idea how to name those methods?

A better practice is to instantiate an object that remembers the record number. When destroyed (if by release method or simply going out of scope) it resets the record number.
