1. A computer-implemented method, comprising:

  • at a computing device with a touch screen display,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;

    wherein 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;

    a heuristic for determining that the one or more finger contacts correspond to a command to transition from a displaying a respective item in a set of items to displaying a next item in the set of items;

    a heuristic for determining that the one or more finger contacts correspond to a command to transition from displaying the respective item in a set of items to displaying a previous item in the set of items;

    a heuristic for determining that the one or more finger contacts correspond to a command to display a keyboard primarily comprising letters; and

    a heuristic for determining that the one or more finger contacts correspond to a command to show a heads up display.
