A user may control automatic zooming and scrolling functionality with respect to a selected point in the document. A user may provide a first input to select an anchor point in the document. A user may then provide a second input to indicate a zooming level. In response to the second input, the document may zoom in or out of the document (depending on the input) and simultaneously perform scrolling to adjust the displayed center of the document towards the anchor point. The scrolling and zooming functions are performed automatically in response to the second input. In some embodiments, a custom zoom cursor may be displayed during a zoom state and change to indicate the zooming function performed. In some embodiments, the input device may be a pointing device such as a mouse, or another type of input device such as a keyboard, touch screen or other device.
