Description
ControlKeyUp is a method used to detect and handle key up events
for navigation keys used in the control. ControlKeyUp calls the corresponding
method in TApplication to determine the actions needed for the key and
modifier. The application handles Return (Enter) and Escape keys which may
affect control or form focus.
ControlKeyUp is called from the DoRemainingKeyUp method to handle keys not otherwise handled by a control or its parent forms.
