  1. Pre-process stage. The input manager raises the PreProcessInput event.

  2. Pre-notify stage. The input manager raises the PreNotifyInput event.

  3. The WPF input event or events are raised.

  4. Post-notify stage. The input manager raises the PostNotifyInput event.

  5. Post-process stage. The input manager raises the PostProcessInput event.
