Notes to Inheritors: HwndSource implements this member as an explicit interface definition to provide basic support for IKeyboardInputSink members. These IKeyboardInputSink members support keyboard operations for interoperation, and include functionality such as raising WPF routed events in response to Win32 messages, and forwarding tab requests. If you are creating instances of the HwndSource class, you do not need to call this member. However, if you are deriving from HwndSource, and you have advanced scenario requirements for keyboard input interoperation, you might need to re-implement System.Windows.Interop.IKeyboardInputSink.TabInto. This requires that you specifically implement IKeyboardInputSink again on your class, and define a new explicit TabInto that overrides the HwndSource version.
