titlestyle="text-decoration: none;"

Between the quotation marks you can use css code to define the style of the titles. This style will be attached to the <a> link of the title link. This won't change the general look of the fact's title, this will add a style only to the title in the fact, where the folder or the fact is included.

For example:

"text-decoration: none;" can be replaced with "color:#cc0000; font-style:italic;" etc.
