\wxheading{Event handling}
+The following commands are processed by default event handlers in wxTextCtrl: wxID\_CUT, wxID\_COPY,
+wxID\_PASTE, wxID\_UNDO, wxID\_REDO. The associated UI update events are also processed
+automatically, when the control has the focus.
+
To process input from a text control, use these event handler macros to direct input to member
functions that take a \helpref{wxCommandEvent}{wxcommandevent} argument.

Under Windows, if the {\bf wxTE\_MULTILINE} style is used, the window is implemented
as a Windows rich text control with unlimited capacity. Otherwise, normal edit control limits
apply.
