Menu/toolbar event handling now tries the window with the focus first.

wxTextCtrl processes cut, copy, paste, undo, redo commands and UI updates
automatically.

+\subsection{Redirection of command events to the window with the focus}
+
+The usual upward search through the window hierarchy for command event
+handlers does not always meet an application's requirements. Say you have two
+wxTextCtrl windows in a frame, plus a toolbar with Cut, Copy and Paste
+buttons. To avoid the need to define event handlers in the frame
+and redirect them explicitly to the window with the focus, command events
+are sent to the window with the focus first, for
+menu and toolbar command and UI update events only. This means that
+each window can handle its own commands and UI updates independently. In
+fact wxTextCtrl can handle Cut, Copy, Paste, Undo and Redo commands and UI update
+requests, so no extra coding is required to support them in your menus and
+toolbars.
