Ah and if what Ingredient says doesn't work, maybe try switching the keys to something a bit easier, beause those keys could be a bit sensitive or sticky. To change the keys, go to options at the front page or by hitting esc then go to controls and scroll down to where it says cam, press whichever one you would like to change and press"change" then press the key you would like to change it to like "k". I hope this helps, just let me know! If you need anything else, just ask.
