An electronic device that is in communication with a display generation component, and sensor(s) to detect location of an input object displays a content selection object within selectable content, wherein the content selection object includes a first edge and a second edge. The device detects an input by the input object, including detecting the input object at a first hover location that corresponds to the first edge of the content selection object. In response to detecting the first portion of the input: in accordance with a determination that the first portion of the input meets first criteria that require the input object meets proximity criteria with respect to the content selection object, the device changes an appearance of the first edge relative to the second edge of the content selection object to indicate that the first edge will be selected for movement when the input object meets second criteria.
