10. The non-transitory computer-readable storage medium of claim 1 , wherein the executable instructions further cause the electronic device to, after displaying the second application:

display content within the first application or the second application;

detect a gesture on the touch-sensitive display, at a location of the displayed content, the gesture moving towards an edge of the touch-sensitive display;

in response to detecting the gesture, determine whether the gesture has moved to within a predetermined distance of an edge of the touch-sensitive display; and

upon determining that the gesture has moved to within the predetermined distance of the edge, temporarily display the updated application selector with the second plurality of affordances.

11. The non-transitory computer-readable storage medium of claim 10 , wherein the executable instructions further cause the electronic device to:

detect movement of the gesture towards a displayed affordance of the second plurality of affordances within the updated application selector, wherein the displayed affordance corresponds to a third application;

detect a liftoff of the gesture from the touch-sensitive display; and

in response to detecting the liftoff, open the third application and display the content within the third application.

12. The non-transitory computer-readable storage medium of claim 10 , wherein the second plurality of affordances is filtered to display affordances corresponding only to applications capable of displaying the content.

13. The non-transitory computer-readable storage medium of claim 1 , wherein the executable instructions further cause the electronic device to, while displaying the application selector:

detect an additional input at an affordance displayed within the application selector, wherein the additional input lasts for an amount of time;

determine whether the amount of time satisfies a threshold amount of time;

upon determining that the amount of time satisfies the threshold amount of time, display a remove affordance within the application selector; and

detect a fourth input at the remove affordance and, in response to detecting the fourth contact, remove the affordance from the application selector.

14. The non-transitory computer-readable storage-medium of claim 1 , wherein:

the displaying the application selector includes displaying the application selector in a predefined portion of the touch-sensitive display; and

the displaying the second application, in response to detecting the input at the affordance, includes displaying the second application in the predefined portion of the touch-sensitive display that was previously used to display the application selector.

15. The non-transitory computer-readable storage-medium of claim 1 , wherein the executable instructions further cause the electronic device to:

in response to detecting the input at the affordance:

cease to display the first application in the full screen mode.

16. The non-transitory computer-readable storage-medium of claim 15 , wherein the displaying the second application includes:

resizing the first application such that it occupies a first portion of the touch-sensitive display; and

displaying the second application in a second portion of the touch-sensitive display that borders the first portion.

17. A method, comprising:

at an electronic device with a touch-sensitive display:

displaying a first application in a full-screen mode on the touch-sensitive display;

detecting, via the touch-sensitive display, a first swipe gesture that includes movement of a contact over at least part of the first application;
