Abstract: The information navigation interface facilitates receiving an indication of a discrete physical contact event with a user input device. The contact event is associated with a user request for navigating an assembly of displayable information. A navigation action based on the received indication is then determined. The navigation action may include either (a) both scrolling and expansion of currently displayed information wherein the scrolling and expansion occur simultaneously or nearly simultaneously, or (b) both scrolling and contraction of currently displayed information wherein the scrolling and contraction occur simultaneously or nearly simultaneously. Once determined, the navigation action is applied, resulting in a display of a second portion of the assembly of information.
