Hi,

Open your theme functions.php file and following filter at the bottom:

add_action('stec_after_html', function() {
    ?>
    <script type="text/javascript">
        (function ($) {
            $.stecExtend(function (m) {
                m.eventsHandler.eventToggle = function (e) {
                    window.open(e.data('permalink'), '_self');
                    return false;
                };
            });
        })(window.jQuery);
    </script>
    <?php
});
