73//
74// Left Mouse: Click to increase speed.
75//
76// <s> + Left Mouse: Alternative to the Seek button. Press (but do not
77// hold down) the <s> key, then click on a target object.
78//
79// <U> + Left Mouse: Press (but do not hold down) the <U> key, then
80// click on a target object to set the "up" direction to the surface normal.
81// By default +y is the "up" direction.
82//
83// Middle Mouse: Click to decrease speed.
84//
85// Left and Middle Mouse: Click boths simultaneously to stop.
86//
87// Ctrl: Hold the key down to temporary stop and rotate the viewpoint.
