Exclude-Event-List
If this property is set to "1", then none of the events in the Event-List property are fired. If this property is set to "0", then only the events listed in the Event-List property are fired. If it’s omitted, then all the events are fired. Preventing the runtime from generating some events may speed up performance in client/server environments.
Note - Excluding focus change events like CMD-GOTO and MSG-VALIDATE may avoid AFTER and BEFORE embedded procedures to be triggered.
 
Example - Define a web-browser control with a list of excluded events
screen section.
