What keys do I use to setup my system?

Made popular by Quake, WASD (also known as Was-duh, or WSAD) is a set of four keys on the left-hand side of a QWERTY or QWERTZ computer keyboard often used to control the player's movement in first-person/third-person (FPS/TPS) computer games. W/S control forward and backward and A/D control strafing left and right. These mimic the arrow keys, which are also commonly used for movement. A variation is W-A-X-D, used by people who are used to the arrows on the numeric keypad (which has the down arrow a line below the left/right arrows, instead of in between).
