To prevent disorientation, the described systems and methods continuously maintain a visual landmark during electronic navigation of a one-dimensional list of items or a two-dimensional information grid in situations where only a part of the list or the information grid is displayed at a given time. In one implementation, an electronic program guide is dynamically scaled to maintain visibility of a navigation starting point during browsing with rudimentary navigation controls, but reverts back to a legible scale when navigation stops.
