When the “Current Page Number” placeholder sits on a master page, every page to which you assigned that specific master page will display this variable – the number will change automatically on every page. If you change the style assigned to the placeholder on the master page (let’s say you set it to bold), all page numbers will update to that style (all numbers will become bold).

In bulleted lists, each paragraph begins with a bullet character. In numbered lists, each paragraph begins with an expression that includes a number or letter and a separator such as a period or parenthesis. The numbers in a numbered list are updated automatically when you add or remove paragraphs in the list. You can change the type of bullet or numbering style, the separator, the font attributes and character styles, and the type and amount of indent spacing.
