Abstract: In one aspect of the invention, a computer-implemented method in a portable multifunction device with a touch screen display includes: displaying content on the touch screen display, wherein the content includes a plurality of user input elements; detecting a contact by a finger with the touch screen display; choosing a user input element in the plurality of user input elements based on proximity of the user input element to the contact; displaying information associated with the chosen user input element over the displayed content; detecting a break in the contact by the finger with the touch screen display; and receiving input for the chosen user input element.

Abstract: A computer-implemented method for use in conjunction with a computing device with a touch screen display comprises: detecting one or more finger contacts with the touch screen display, applying one or more heuristics to the one or more finger contacts to determine a command for the device, and processing the command. The one or more heuristics comprise: a heuristic for determining that the one or more finger contacts correspond to a one-dimensional vertical screen scrolling command, a heuristic for determining that the one or more finger contacts correspond to a two-dimensional screen translation command, and a heuristic for determining that the one or more finger contacts correspond to a command to transition from displaying a respective item in a set of items to displaying a next item in the set of items.
