Aim, sweep and look?

[Vinilux¼]

So, what is the difference between these three options? I still don't get it. I tunk look is the fastest when moving and is a quick look at an area or something.

What does the focusing on an area do?
Thanks in advance.

basically like the original as far as i can tell . You tell them to focus on an enemy or area and they wont look around at other areas or enemies or tell them to ignore an enemy or area. Look i bleieve is just like the check command of the original, they will give a quick glance to what ever direction you want[check corners] . Now aim and sweep i'm not as clear on and would like an explanation of the differences myself.

aim makes you look always in the same direction
focus on the area makes you follow with the sight a given point on a map while moving around
little difference actualy, since the speed is slow
quick look is a quick look aside without changing your original stance
