\membersection{wxEvent::Skip}\label{wxeventskip}
\func{void}{Skip}{\param{bool}{ skip = true}}
-Called by an event handler to tell the event system that the
-event handler should be skipped, and the next valid handler used
-instead.
+This method can be called by an event handler and controls whether additional
+event handlers bound to this event will be called after the current event
+handler returns. The default behavior is equivalent to calling Skip(false)
+(which is, hence, usually unnecessary) and 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. If Skip(true) is
+called, the event processing system continues searching for a handler
+function for this event as if the current handler didn't exist.
+
+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.
