- # BeginExtend --
- #
- # This procedure is typically invoked on shift-button-1 presses. It
- # begins the process of extending a selection in the listbox. Its
- # exact behavior depends on the selection mode currently in effect
- # for the listbox; see the Motif documentation for details.
- #
- # Arguments:
- # w - The listbox widget.
- # el - The element for the selection operation (typically the
- # one under the pointer). Must be in numerical form.
