Not Close Enough?

Look in the controls menu. It has the ability to assign a key to each action you wish to perform. As with most games, by default, W makes you walk forward, A makes you strafe left, D makes you strafe right, and S makes you backpace. I call the keys my WADS instead of WASD becuase it sounds cooler.

Also use the spacebar to jump, the ctrl key to toggle crouching, and holding down shift while walking in any direction to run.
