How do I change the word "number" in Oder Datils view SEF URL?

[Genius WebDesign]

Hi,

Regarding the order details view, the SEF URL generated looks like this:
http://www.mysite.net/da/ordreoversigt/number/1a5a03

My question is, how do I change this part of the URL: /number/ to /info/ ?

perhaps

if ( isset($query['order_number']) ) {
            $segments[] = 'number/'.$query['order_number'];
            unset ($query['order_number'],$query['layout']);
         } else if ( isset($query['virtuemart_order_id']) ) {
            $segments[] = 'id/'.$query['virtuemart_order_id'];
            unset ($query['virtuemart_order_id'],$query['layout']);
         }

components\com_virtuemart\router.php  ~ line 266 - no idea what side effects it may have

Thanks, I will give it a try if needed.
May be my client can live with the current URL structure (I hope).
