| * - Keyboard: Dispatch to the embedder responder and the channel responder |
| * simultaneously. After both responders have responded (asynchronously), the |
| * event is considered handled if either responder handles. |

| * synchronously. |
| * - Next responder: Events are sent to the next responder as specified by |
| * |viewDelegate|. |
