A method, comprising: at an electronic device with a touch-sensitive surface, a display, and one or more sensors to detect intensities of contacts on the touch-sensitive surface: presenting on the display, in a user interface, a first portion of structured content, wherein the structured content includes a plurality of sections, and the first portion includes content from a first section of the plurality of sections; while presenting the user interface on the display: detecting a first contact on the touch-sensitive surface while the first portion of the structured content is presented on the display; detecting an increase in a characteristic intensity of the first contact on the touch-sensitive surface and detecting a first movement of the first contact on the touch-sensitive surface; and, in response to detecting the increase in the characteristic intensity of the first contact and detecting the first movement of the first contact: in accordance with a determination that the characteristic intensity of the contact increases above a first intensity threshold, reducing a size of the first portion of the structured content on the display, and translating the structured content to display a start of a second section adjacent to the first section of the structured content at a predefined location on the display; and, in accordance with a determination that the characteristic intensity of the contact does not increase above the first intensity threshold, translating the structured content within the user interface in accordance with a magnitude of the movement of the contact on the touch-sensitive surface. presenting on the display, in a user interface, a first portion of structured content, wherein the structured content includes a plurality of sections, and the first portion includes content from a first section of the plurality of sections; while presenting the user interface on the display: detecting a first contact on the touch-sensitive surface while the first portion of the structured content is presented on the display; detecting an increase in a characteristic intensity of the first contact on the touch-sensitive surface and detecting a first movement of the first contact on the touch-sensitive surface; and, in response to detecting the increase in the characteristic intensity of the first contact and detecting the first movement of the first contact: in accordance with a determination that the characteristic intensity of the contact increases above a first intensity threshold, reducing a size of the first portion of the structured content on the display, and translating the structured content to display a start of a second section adjacent to the first section of the structured content at a predefined location on the display; and, in accordance with a determination that the characteristic intensity of the contact does not increase above the first intensity threshold, translating the structured content within the user interface in accordance with a magnitude of the movement of the contact on the touch-sensitive surface. detecting a first contact on the touch-sensitive surface while the first portion of the structured content is presented on the display; detecting an increase in a characteristic intensity of the first contact on the touch-sensitive surface and detecting a first movement of the first contact on the touch-sensitive surface; and, in response to detecting the increase in the characteristic intensity of the first contact and detecting the first movement of the first contact: in accordance with a determination that the characteristic intensity of the contact increases above a first intensity threshold, reducing a size of the first portion of the structured content on the display, and translating the structured content to display a start of a second section adjacent to the first section of the structured content at a predefined location on the display; and, in accordance with a determination that the characteristic intensity of the contact does not increase above the first intensity threshold, translating the structured content within the user interface in accordance with a magnitude of the movement of the contact on the touch-sensitive surface. in accordance with a determination that the characteristic intensity of the contact increases above a first intensity threshold, reducing a size of the first portion of the structured content on the display, and translating the structured content to display a start of a second section adjacent to the first section of the structured content at a predefined location on the display; and, in accordance with a determination that the characteristic intensity of the contact does not increase above the first intensity threshold, translating the structured content within the user interface in accordance with a magnitude of the movement of the contact on the touch-sensitive surface.
