Hi Milos,
It's navigation text of Owl Carousel used in JA VM Product module, you can edit this file:
/templates/ja_techzone/html/mod_javmproducts/default.php
Look for the script at the end of this file and add navigation-text value as below:
<script>
(function($){
jQuery(document).ready(function($) {
$("#javm_slider<?php echo $module->id;?>.owl-carousel").owlCarousel({
navigation : true,
navigationText : ["prev", "next"],
pagination: false,
items: <?php echo $params->get('display_items', '4'); ?>,
loop: false,
scrollPerPage : true,
itemsDesktop : [1199, 3],
itemsDesktopSmall : [979, <?php echo $params->get('display_items_tablet', '2'); ?>],
itemsTablet : [768, <?php echo $params->get('display_items_tablet', '2'); ?>],
itemsTabletSmall : [600, <?php echo $params->get('display_items_mobile', '1'); ?>],
itemsMobile : [479, <?php echo $params->get('display_items_mobile', '1'); ?>]
});
});
})(jQuery);
</script>
and change the 'prev' and 'next' to your desired text.
