In some embodiments, an electronic device with a display and a touch-sensitive surface displays a user interface object. The device detects a first contact and a second contact concurrently on the touch-sensitive surface. The device determines which contact of the first contact and the second contact is a topmost contact, a bottommost contact, a leftmost contact, and a rightmost contact on the touch-sensitive surface. While continuing to detect the first contact and the second contact, the device detects movement of the first contact across the touch-sensitive surface, and concurrently moves two edges of the user interface object that correspond to the first contact in accordance with the detected movement of the first contact, including horizontally moving one of the two edges and vertically moving the other of the two edges.
