Scroller

I am not an experienced Joomla user but slowly I reveal the secrets of this template, the site gets more and more the look I want, I still have a little problem withe the scroller. How does the scroller gets his lines? I mean where do the the words in the scroller come from. If I know how this works I can change the lines and also use the scroller.

From articles, you select content source type and content source ID which can be category or articles . Read descriptions in tooltip boxes when you are over field in module settings.
