An interface prompts a user to enter a marker during a communications session, in which the user is able to later provide a subsequent version of the marker. Initially, a first version of the marker is received from the user. A processor associates the first version of the marker received from the user with a particular position in an information tree and stores the particular position in the information tree associated with the first version of the marker. A second version of the marker is received from the user and in response, the user is returned to the particular position in the information tree that has been stored and associated with the first version of the marker received from the user.
