Mouselook
The Mouselook (or first person) view can be obtained by pressing "m" on the keyboard when the chat bar is closed. Press Esc to return to the normal (third person) view.
The keyboard and mouse take on special behavior in mouselook. Left and right direction controls move side to side as if the Shift key was held down, while mouse movement is used to rotate. Left mouse clicks work normally. To view the pie menu in mouselook, hold down the Alt key (Option on Mac) while right clicking.
