ITfContextKeyEventSink interface (msctf.h)
The ITfContextKeyEventSink interface is implemented by a text service to receive keyboard event notifications that occur in an input context. This keyboard event sink differs from the ITfKeyEventSink keyboard event sink in that the keyboard events are passed to ITfContextKeyEventSink after having been preprocessed by the ITfKeyEventSink event sink. Preserved key events and filtered key events are not passed to the ITfContextKeyEventSink event sink.
This event sink is installed by ITfSource::AdviseSink with IID_ITfContextKeyEventSink.
