+# This procedure is typically invoked on control-button-1 presses. It
+# begins the process of toggling 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.
