Viewing an electronic document in a display window of a display may include detecting a layout of the electronic document (505) and comparing the layout of the electronic document to a width of the display window (510). The electronic document may be reformatted into at least two columns, with each of the columns having a width that does not exceed a width of the display window (515). Navigating on the display may include tracking motion of an input tool on a display, comparing a motion of the input tool to a threshold, and changing a position of the visible portion of a page of information on the display if the input tool motion exceeds the threshold. The position of the visible portion of the page of information on the display may be constrained if the motion does not exceed the threshold. Navigating on a display also may include tracking coordinate information of an input tool on a display and moving a visible portion of a page of information on the display a distance equal to a change in the coordinate information of the input tool multiplied by a multiplier. Navigating on a display also may include providing a navigation control operable to change a viewable portion of a page of information on a display from a first view to a second view. In response to operation of the navigation control, the display may be animated to create an appearance of motion as the viewable portion of the page of information changes from the first view to the second view in response to operation of the navigation control.
