ABSTRACT:
A rendering engine that supports directional focus navigation, in response to a directional input, shifts the focus to an appropriate focusable element. The rendering engine determines one or more focusable elements that are candidates to receive the focus based on the received directional input and based on the relative display locations of the focusable elements. The rendering engine selects the most appropriate candidate focusable element based on each candidate element's display location in relation to the display location of the element that currently has focus.
