To show a point's calculation path
Hold down the CTRL and SHIFT keys as you click the point in a fractal.
The calculation path appears in white. You can move the pointer while the CTRL and SHIFT keys are held down to see how the calculation path changes for different points in a fractal.
The status bar (in the lower-left corner of Fractal eXtreme's workspace window) displays whether a cycle exists at the selected location in the fractal. If one exists, it displays the length of the cycle.
