Do you often find yourself meeting a player killer on the way back to town? You try to get around them, but they keep moving in front of you! Well, there's a way you can "sidestep" or "move diagonal" twice, to pass them.
Your first step is to drag yourself with your mouse, in a diagonal direction towards their side. You will pause for a moment, then move in the direction of which you dragged the mouse. Your second step is to hit the number pad arrow in the direction to fall back into line, on their other side.
