Slider controls customization

Hi to all,
i would like to ask how to move or delete the slider controls. I’m using flex slider i would like to move the controls to the slider or i dont want it. So the question is where can i find in the php files the part that is solving the flex-control navigation?

Basically i want this part:

<ol class=”flex-control-nav flex-control-paging”>
“navigation”
<ul class=”flex-direction-nav”>

that is generated with the php away or i want the part to be in the ul slider section that is located in the functions.php
Thanks for responses… Caen
