Abstract: An electronic device displays a content region including first content that contains an image; and, while displaying the first content, detects an input at a location that corresponds to the location of the image. In response, the electronic device, in accordance with a determination that the input includes an intensity above a respective threshold and that the image is associated with a link to second content that is different from the first content, displays a preview of the second content while maintaining display of at least a portion of the first content in the content region; and, in accordance with a determination that the input includes an intensity above the respective threshold and that the image is not associated with a link to additional content, displays an enlarged version of the image while maintaining display of at least a portion of the first content in the content region.

Abstract: An electronic device, while displaying a user interface that corresponds to at least a portion of a web page on a display, detects a touch input on a touch-sensitive surface at a first location that corresponds to the displayed portion of the web page on the display. While detecting the touch input on the touch-sensitive surface, the electronic device detects an intensity of the touch input on the touch-sensitive surface, determines whether the intensity of the touch input on the touch-sensitive surface has changed from below a first intensity threshold to above the first intensity threshold, and in response to determining that the intensity of the touch input on the touch-sensitive surface has changed from below the first intensity threshold to above the first intensity threshold, generates a force down event that is distinct from a mouse down event.
