Adding previous/next keyboard shortcut

Hey kilimats!

Thank you for using Enfold.

Please add this in the functions.php file:

// custom script
add_action( 'wp_footer', 'ava_custom_script' );
function ava_custom_script() {
	?>
	<script type="text/javascript">
	(function($) {
		function a() {
		    jQuery(document).keydown(function(e) {
		        var url = false;
		        if (e.which == 37) {  // Left arrow key code
		            url = jQuery('.avia-post-prev').attr('href');
		        }
		        else if (e.which == 39) {  // Right arrow key code
		            url = jQuery('.avia-post-next').attr('href');
		        }
		        if (url) {
		            window.location = url;
		        }
		    });
		}

		a();
	})(jQuery);
	</script>
	<?php
}

Best regards,
