Fly cam is another useful way to explore your surroundings. To enable it, hold down your right mouse button (RMB). You can then use the A and D keys to pan from side, the R and C keys to pan up and down, and the W and S keys to zoom in and out. You can also orbit items in this mode by moving your mouse. The camera can be returned to its original, avatar-locked position by pressing the Esc key twice.
