The object can be moved with either the mouse or with specific keystrokes.
Moving the Object with the Mouse
Left-clicking and dragging the mouse will move the object as if the screen is the front of a "trackball". Moving the mouse up will rotate the object up about its center, and vice versa. Moving the mouse to the left or right will rotate the object left or right about its center.
Right-clicking and dragging the mouse will translate the object in the direction the mouse is moving.
