You can change cameras with the following keys:

   N        switch to next camera
   P        switch to previous camera
   R        switch back to third-person camera

   There are two cameras implemented: a third person camera, and the debug camera.

The debug camera was remapped:

   A                Rotates camera left (relative to camera’s current orientation)
   D                Rotates camera right (relative to camera’s current orientation)
   W                Moves camera forward (do not change elevation (i.e., Y-coordinate))
   S                Moves camera backward (do not change elevation (i.e., Y-coordinate))
Page Up             Tilts camera up
Page Dn             Tilts camera down
   Q                Moves camera up (increase Y-coordinate of camera) (do not change X- or Z-coordinate)
   Z                Moves camera down (decrease Y-coordinate of camera) (do not change X- or Z-coordinate)
