Underneath the headline are any number of headlines, each of which contains the name of a setting. Subordinate to the heading is the value of the setting. Values are evaluated, so they may contain script code. The names are taken as literals, so spaces count. Look at user.slideShow.outlines.frontier5rollout for an example of a slide show that contains settings comments.
Some settings apply only to slide shows.
