FGColor	No	The foreground color of the applet. This applies to the labels and should normally be the same as the font color of the web page. You may set it to any RGB hex color code just as you would do with the HTML font tag (for example #000000)

VisibleAmount	No	The visible amount of the scrollbar's slider button. Default is 10.
