Graphing options

Thanks! Cool feature! Like it!

On the CASIO fx-9860GII graph itself, one can pick a "y" value, and the firstmost "x" on the graph that satisfies "y" is displayed on the graph with the x,y coordinate displayed on the bottom of the display. If another "x" value that satisfies "y" exists on the graphview, pressing on the directional disk to the right makes the curser jump to the next "x" that satisfies "y" with it's coordinates displayed on the bottom of the display.
