Rattler (DayZ)

Hey guys.. I have some how managed to press this button that removes the UI of how much fuel your car has, how broken it is, and the speed meter. I'd love to see how broken my car is and how fast I'm driving but I have no clue what I've done, or what to do to make the hud come back. Thanks for your help !

I think I screwed up a little with the UI. The thing is, when you're in the first person mode and double click on "left alt" you can look without moving your body. But I've somehow activated that option all the time. It's kind of hard to explain, but you know the green option thingy that pops up when you are looting something? Or the weapon symbol you get when you're about to. Well that text keeps moving around when I move my mouse, and it takes a while before my character moves because I have to put my cursor in the end of the screen first.. GOD this is hard to explain but I hope you understand what I mean.. I'd love to get an answer from you guys.

Thank you so much for all the answers, and Mr. Beanking was right. GOD I were a bit suicidal there, thanks alot!
