Abstract
A method and an apparatus that keeps track of locations in an electronic file that is represented as a hierarchical data structure, generate a point dictionary to store points that point to locations, and generate point identifiers to access the points in the point dictionary. Point identifiers are stored by ancillary routines and with components in the electronic file's data structure. The points in the dictionary change as locations in the electronic file change, but the point identifiers do not change. The point identifiers stored with the components in the electronic file's data structure enable the method and the apparatus to retrieve other points in the same component without conducting a search through the point dictionary.
