A method, comprising: at an electronic device with a touch-sensitive display (450,112), wherein the device includes one or more sensors to detect intensity of contacts with the touch-sensitive display (451,112): displaying, on the touch-sensitive display (450,112), first content; while a contact is detected at a first location on the touch-sensitive display (450,112) that is associated with a bounded area of the first content, detecting an increase in the intensity of the contact on the touch-sensitive display (450,112) above a respective intensity threshold (IT L); and in response to detecting the increase in intensity of the contact on the touch-sensitive display (450,112) above the respective intensity threshold (IT L), displaying in the bounded area, content that gives a visual appearance of being viewed through a virtual loupe in place of the portion of the first content that was within the bounded area; detecting movement of the contact on the touch sensitive display (450,112) to a second location on the touch-sensitive display (450,112): in response to detecting said movement of the contact on the touch sensitive display (450,112), moving the bounded area in accordance with the movement of the contact and changing the content displayed within the bounded area as the contact is moved, such that the content in the bounded area continues to give the visual appearance of being viewed through the virtual loupe; detecting a decrease in intensity of the contact to an intensity at or below the respective intensity threshold (IT L) without detecting liftoff of the contact from the touch-sensitive display (450,112); and, in response to detecting the decrease in intensity of the contact, redisplaying the portion of the first content that was displayed at the location of the bounded area prior to movement of the contact to that location. displaying, on the touch-sensitive display (450,112), first content; while a contact is detected at a first location on the touch-sensitive display (450,112) that is associated with a bounded area of the first content, detecting an increase in the intensity of the contact on the touch-sensitive display (450,112) above a respective intensity threshold (IT L); and in response to detecting the increase in intensity of the contact on the touch-sensitive display (450,112) above the respective intensity threshold (IT L), displaying in the bounded area, content that gives a visual appearance of being viewed through a virtual loupe in place of the portion of the first content that was within the bounded area; detecting movement of the contact on the touch sensitive display (450,112) to a second location on the touch-sensitive display (450,112): in response to detecting said movement of the contact on the touch sensitive display (450,112), moving the bounded area in accordance with the movement of the contact and changing the content displayed within the bounded area as the contact is moved, such that the content in the bounded area continues to give the visual appearance of being viewed through the virtual loupe; detecting a decrease in intensity of the contact to an intensity at or below the respective intensity threshold (IT L) without detecting liftoff of the contact from the touch-sensitive display (450,112); and, in response to detecting the decrease in intensity of the contact, redisplaying the portion of the first content that was displayed at the location of the bounded area prior to movement of the contact to that location. in response to detecting said movement of the contact on the touch sensitive display (450,112), moving the bounded area in accordance with the movement of the contact and changing the content displayed within the bounded area as the contact is moved, such that the content in the bounded area continues to give the visual appearance of being viewed through the virtual loupe; detecting a decrease in intensity of the contact to an intensity at or below the respective intensity threshold (IT L) without detecting liftoff of the contact from the touch-sensitive display (450,112); and, in response to detecting the decrease in intensity of the contact, redisplaying the portion of the first content that was displayed at the location of the bounded area prior to movement of the contact to that location.
