Abstract
An e-book (112) has navigation controls (124) for accessing the sections (110) of a first path (130) of sections of the e-book. In response to receipt (101) of a path-change command (134), the active path (129) is changed to a second path (132). Concomitantly, the navigation controls are changed so that they provide for navigation along the second path instead of along the first path.
