"The Control panel allows you to change position, distance (from your location body), (viewing) direction, roll angle and zoom. You can do this in steps from the keyboard (arrow keys), or set the change stepping continuously. We have selected to control direction (this is the default) and our view steps round until we see Jupiter in the sky."

"Here we have switched to changing distance in steps to move us further from the Earth - sometimes more useful than zooming out. If you open the Control panel fully (click the button in the top right of the panel), you will see other aim controls. These allow you to step or play continuously the chosen control function, and to choose coordinate systems for changing aim."
