An electronic device displays a user interface of a first software application that includes one or more draggable objects and one or more control objects; and, detects a contact on a touch-sensitive surface at a first location while a focus selector is displayed over a first draggable object and a movement of the contact across the touch-sensitive surface to a second location that corresponds to a first control object. In accordance with a determination that the contact at the first location satisfies object selection criteria, the device moves the first draggable object to the first control object in accordance with the movement of the contact across the touch-sensitive surface to the first control object. In accordance with a determination that the contact at the second location satisfies first intensity criteria, the device performs a first predetermined operation that corresponds to activation of the first control object.
