The mouse mode determines what happens when you click inside the fractal window. In Switch mode, a mouse click switches between related fractal types.
To enter Switch mode, click Switch Mode on the Fractal menu, or make sure the Switch Mode button on the toolbar is down.
Switching is typically used with Mandelbrot and Julia-like fractals. The Mandelbrot set is actually a map of Julia sets. Each point in the Mandelbrot set corresponds to a unique Julia set. The shape of this Julia set reminds of the immediate surroundings of the corresponding point in the Mandelbrot set.
If you enter Switch mode while looking at a Mandelbrot set and move the mouse cursor over the fractal window, the Fractal Mode tool window shows a preview of the corresponding Julia set. Click to open a new fractal window with this Julia set, so you can further explore it.
