Well I'm feeling a bit stupid now, I'm really pretty new to this so things are not so obvious to me as they might be to others. I got confused because of a video I watched where the bloke was moving all around. Now I understand. Sorry for wasting your time and thanks for your responses.

It's party of learning.
