class SomeCommand extends Command

    protected function execute(InputInterface $input, OutputInterface $output)
    {
        // ...

        $cursor = new Cursor($output);

        // argument for top/bottom is "number of rows" (1 by default)
        $cursor->moveUp(2)->moveRight();
        $cursor->moveDown();

        // move to an arbitrary (column, row) position
        $cursor->moveToPosition(7, 15);

        // you can show/hide the cursor, save/restore its position, etc.
        $cursor->savePosition()->hide();
