Examples/Parameter: mode (example 2)

Example
This matches/lists articles that have "Appl" in their name, excluding subpages; pages are ordered by their name regardless of category, and the output is shown in category style (i.e., organized alphabetically, displaying category-style capital letters) because of the  parameter. An  is required when   is set (so DPL3 knows how to order the category listing style), and the  value makes the first letter of the page title the category heading. Note that using instead would cause use of the first letter of the namespace if it exists, and just the title if it doesn't (such as for pages in the Main namespace).
