Heuristic for generating opposite information for inclusion in focus events

摘要

A method for generating information for inclusion in focus events includes maintaining a list of components requesting focus in a selected application, determining whether a target of a first focus event matches a component at a head of the list, and if the target of the first focus event matches the component at the head of the list, marking the component at the head of the list for inclusion in an opposite field of a second focus event.
