An embodiment of the present invention includes a technique to provide multiple focus controls. First and second focus managers manage first and second focus owners, respectively. The first and second focus owners correspond to components of media planes displayable on at least one of a plurality of output display devices. The first and second focus managers associate first and second key events generated by first and second input devices, respectively, to the respective first and second focus owners. A router has a routing table that stores information of association between first and second connections and the first and second focus managers, respectively. The router routes one of the first and second key events originating from the respective connection to a corresponding focus manager using the routing table.
