Priority key events are configured using RWindowGroup::AddPriorityKey() , and obtained by the client using the functions described in Getting priority key events. All priority key events generated by the Window Server are delivered to the client in a TWsPriorityKeyEvent , and the client obtains the priority key event using RWsSession::GetPriorityKey() .
Priority key events are typically used for providing "Abort" or "Escape" keys for an application.
