Hello DanMoore, I assume you are referring to earlier today, when you saw me and Boozie and Waggot all moving REALLY fast to that temple thing. That was called strafe jumping as Garret said. To perform this you must be running forward with "w" and holding either "a" or "d" so that you are sort of running diagonal-ish, and then you jump while holding all of these. This will make you move really fast, and learning the timing of when to hit the jump key is based on practice.
