# DataExtend
#
# This procedure is called for key-presses such as Shift-KEndData.
# If the selection mode isn't multiple or extend then it does nothing.
# Otherwise it moves the active element to el and, if we're in
# extended mode, extends the selection to that point.
#
# Arguments:
# w - The listbox widget.
# el - An integer element number.
