Abstract: A computing device with a touch screen display simultaneously displays on the touch screen display a plurality of user interface objects displayed at a first magnification level in a display area. The device detects a first contact on a first handle activation region for a first handle of a user interface object. In response to continuing to detect the first contact at for a predefined amount of time, the device zooms the display area to a second magnification level. While the display area is at the second magnification level, the device: detects a movement of the first contact across the touch screen display; moves the first handle in accordance with the detected movement of the first contact; and detects liftoff of the first contact. In response to detecting liftoff of the first contact, the device zooms the display area to the first magnification level.
