-Called by an event handler, it controls whether additional event
-handlers bound to this event will be called after the current event
-handler returns.  Skip(false) (the default setting) will prevent
-additional event handlers from being called and control will be
-returned to the sender of the event immediately after the current
-handler has finished.  Skip(True) will cause the event processing
-system to continue searching for a handler function for this event.
+This method can be used inside an event handler to control whether further
+event handlers bound to this event will be called after the current one
+returns. Without Skip() (or equivalently if Skip(false) is used),
+the event will not be processed any more. If Skip(true) is called, the event
+processing system continues searching for a further handler function for this
+event, even though it has been processed already in the current handler.
+
+In general, it is recommended to skip all non-command events to allow the
+default handling to take place. The command events are, however, normally not
+skipped as usually a single command such as a button click or menu item
+selection must only be processed by one handler.
