Customizing 'orderby'

[Menace]

Hello,

I am working on a site with VM 3.0.4 with Joomla! 3.3.6 and I am new to VM3.

Coming from VM2 I wonder where I can find the file that contains the div structure of the 'orderby' function. It used to be coded in the category.php itself but now it is called by $this->orderByList['orderby'].
Where can I find this and can override be used?

called in components\com_virtuemart\views\category\view.html.php

$this->orderByList = $productModel->getOrderByList($this->categoryId);

administrator\components\com_virtuemart\models\product.php
function getOrderByList ($virtuemart_category_id = FALSE)
