I haven't found a way to scroll with a footswitch, except that my Ketron SD1 will do that if you load the lyrics into the keyboard harddrive. You name the style and the text file the same, and they both open together. Very neat, but I haven't chosen to use that feature except to try it out.

You don't actually use the Properties to sort. Rather, you use the Properties to save the song name, artist, genre or whatever else you want to enter. Then, MSWord allows you to sort by merely clicking on the appropriate bar at the top of the page.
