Next/prev navigation in Lightbox

Hi,

nice slider!
I use the slide inside the theme file (single.php) using this code:

slideshow($output = true, $gallery_id = false, $post_id = get_the_ID(), $params = array());

is there an option to enable forward / previous navigation inside the lightbox? I know it’s possible with the colorbox jquery plugin. Is there a page with all available options for the shortcode/slideshow() function?

Thanks
Olaf
