Scroller Help

I had a look at he scroller tutorials and they are great. I like the one called “Scrolling Dynamically Loaded Text”. My problem is, and I hope you help me, is that I would like the text to automatically scroll rather than have to use the toolbar to scroll the dynamically loaded text.

If you can also show me how to have different topics stop for a few seconds as they scroll before the next set of text come up.

ALso how can I change the text from scrolling to say maybe fade in and fade out or maybe slide in and slide out?
