Orbits Window Mode The key turns on the orbit mode. In this mode a cursor appears over the fractal. A window appears showing the orbit used in the calculation of the color at the point where the cursor is. Move the cursor around the fractal using the arrow keys or the mouse and watch the orbits change. Try entering the orbits mode with View Windows () turned on. The following keys take effect in orbits mode. Upper case 'C' Circle toggle - makes little circles with radii inversely proportional to the iteration. Press again to toggle back to point-by-point or line mode display of orbits. Upper case 'L' Line toggle - connects orbits with lines. Press again to toggle back to point-by-point or circle mode display of orbits. The circle toggle and line toggle orbit modes may be used simultaneously.
