In some examples, the user interface can be scrolled or scaled in response to a rotation of the crown. The direction of the scrolling or scaling and the amount of scrolling or scaling can depend on the direction and amount of rotation of the crown, respectively. In some examples, the amount of scrolling or scaling can be proportional to the change in rotation angle of the crown. In other examples, a speed of scrolling or a speed of scaling can depend on a speed of angular rotation of the crown. In these examples, a greater speed of rotation can cause a greater speed of scrolling or scaling to be performed on the displayed view. ## Claims ### Claim 1 A non-transitory computer-readable storage medium comprising instructions for: at an electronic device with a housing, a touch-sensitive display, and a physical crown that has a fixed axis about which the physical crown rotates relative to the touch-sensitive display and the housing: receiving crown position information associated with the physical crown of the electronic device including a rotational position of the physical crown;
