A multifunction device displays a plurality of selectable user interface objects. Each respective selectable user interface object has a respective activation region. The device detects a first input; and, in response to detecting the first input, the device selects the first selectable user interface object and the device additionally: deactivates the activation region of the first selectable user interface object, or reduces the activation region of the first selectable user interface object to a smaller area than the default activation region. The device also enlarges an activation region of a selectable user interface object that is adjacent to the first selectable user interface object such that the enlarged activation region of the adjacent selectable user interface object occupies at least a portion of an area previously occupied by the default activation region of the first selectable user interface object.
