in.nature,-in.maritime to appear on posts or pages that belong to category nature but at the same time do not belong to category maritime.
in.nature,-as.strong-language to appear on posts or pages that belong to category nature and are not tagged as strong-language.

dow.5,hour.20-23,as.strong-language to appear on posts and pages that use strong language, but only on Friday evening.

When you finish setting up your URL list, the next step is either to set up a Galdget widget (Appearance / Widgets) or create a shortcode in a page or a post.
