+{\bf Pay close attention to Step 5.}  People often overlook or get
+confused by this powerful feature of the wxWindows event processing
+system.  To put it a different way, events derived either directly or
+indirectly from wxCommandEvent will travel up the containment
+heirarchy from child to parent until an event handler is found that
+doesn't call event.Skip().  Events not derived from wxCommandEvent are
+sent only to the window they occurred in and then stop.
+
+Typically events that deal with a window as a window (size, motion,
+paint, mouse, keyboard, etc.) are sent only to the window.  Events
+that have a higher level of meaning and/or are generated by the window
+itself, (button click, menu select, tree expand, etc.) are command
+events and are sent up to the parent to see if it is interested in the
+event.
