Help screen column header DisplayNum
From Joomla! Documentation
- Display #. This list box shows at the bottom of the screen, below the list of items. You can select the number of items to display on one page. If there are more items than this number, you can use the page navigation buttons (Start, Prev, Next, End, and page numbers) to navigate between pages. Note that if you have a large number of items, it may be helpful to use the Filter options, located above the column headings, to limit which items display.
