Claim:
A method, comprising: at a multifunction device with a display and a touch-sensitive surface: displaying an electronic canvas on the display at a first magnification level, wherein the displayed electronic canvas includes at least one displayed object; simultaneously detecting a first contact at a first location and a second contact at a second location on the touch-sensitive surface, wherein at least one of the first contact location and the second contact location on the touch-sensitive surface is at a location that corresponds to a location on the display that is away from the at least one displayed object; detecting a first gesture made with the first and second contacts on the touch-sensitive surface; in accordance with a determination that a velocity of the first gesture is less than a predefined gesture velocity threshold, scaling the displayed electronic canvas in accordance with the first gesture; and in accordance with a determination that the velocity of the first gesture is greater than the predefined gesture velocity threshold, transitioning the displayed electronic canvas from the first magnification level to a second, predefined magnification level in response to the first gesture.
