@Override
protected void ctrlClickSelect(SelectionModel<JsonObject> model, CellReference<JsonObject> cell, GridClickEvent e) {
	// Plain control click, or no previously selected.
	if (!e.isShiftKeyDown() || previous < 0) {
		super.ctrlClickSelect(model, cell, e);
		previous = cell.getRowIndex();
		return;
	}

	// Stop selecting text for now.
	WidgetUtil.setTextSelectionEnabled(grid.getElement(), false);
	WidgetUtil.clearTextSelection();

	// This works on the premise that grid fires the data available event to
	// any newly added handlers.
	boolean ctrlOrMeta = e.isControlKeyDown() || e.isMetaKeyDown();
	handler = grid.addDataAvailableHandler(new ShiftSelector(cell, model, ctrlOrMeta));

	Range dataAvailable = event.getAvailableRows();

	Range selected = Range.between(min, max + 1);
	Range[] partition = selected.partitionWith(dataAvailable);

	for (int i = partition[1].getStart(); i < partition[1].getEnd(); ++i) {
