Device, method, and graphical user interface for selecting user interface objects

An electronic device with a display, touch-sensitive surface and one or more sensors to detect intensity of contacts with the touch-sensitive surface displays a virtual keyboard, and outputs characters corresponding to respective keys in the virtual keyboard when character-output criteria are met. While displaying an autocorrect user interface for changing a string of characters to a modified string of characters, the device detects an autocorrect input that includes an increase in intensity of a contact above a first intensity threshold while a focus selector is over a respective user interface element in the autocorrect user interface, and then either changes the string of characters to the modified string of characters, or maintains the string or characters, depending on whether the contact has an intensity that meets first predefined criteria with respect to the first intensity threshold and a second intensity threshold that is higher than the first intensity threshold.
