I'm a tad bit stuck

[superduper1]

Ok.. i'm new to this game, it's my first day and i'm a bit stuck. I just rotated the thing to activate the "security system" and I went through to the next part killed some sand people, went up in the multiple levels of the courtyard and through the door on the very top. Now here is my problem. I pulled the switch on the wall to open the door, and I now made my way over the saw, up through the hole in the top, and the door in front of me is slowly closing and I just can't seem to get to it in time. i do this part over and over again very quickly but i can't get to the door. I's usually half way closed by that time. Maybe i'm supposed to roll under it? How do i roll? i'm on a PC by the way.
Thanks for your help.

your suposed to roll under it and to do this run and press the jump button a the same time and you should roll right under the door
