No, they're looking for a way to ORBIT a SELECTION. Moving the mouse moves the camera about the camera's axis and then requires you to use the WASD keys to move about. In many programs, there's a way to ORBIT a selection so, by moving the mouse, you move AROUND the object select, enabling you to easily see it from all sides without having to do fancy maneuvering via WASD+mouse to achieve something similar.
