If you start to type in what appears to be a numbered list, Word formats your manually typed "numbers" to an automatic numbered list. The main benefit of this option is that you do not need to click any button to start numbering and you can choose your numbering style as well. For example, if you type "(a) some text" and press Enter, it starts numbering using the "(a)" format.
InDesign’s automatic page numbers work well enough, but what about special cases? Some documents require pages to be omitted from total page counts. Other documents use several different systems. Sometimes section numbers or special codes must be included. Well, don’t start typing in those numbers manually, because InDesign can handle it—and quite gracefully, too.
Tip: A “page x of y” page number tells you the number of the current page (x) and the total number of pages in the document (y). To create a “page x of y” page number, select Page 1 of 1 in the Page Numbering Format list box. (Note that if you have more than one page in your document when you insert or change the page numbers, the “Page 1 of 1” option may appear in the dialog box as “Page 1 of 2,” “Page 2 of 5,” and so on, depending on the current page and the total number of pages.).
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).
Creating Long Documents with InDesign shows designers how to plan, create, and output book-length documents using InDesign CC features and third-party plugins. Publishing veteran Mike Rankin focuses on long-document elements such as page and chapter numbering, tables of contents, cross-references, and indexes. The course also provides strategies and best practices for document construction, from creating master pages and applying consistent formatting with styles, to placing text and images and outputting to both print and interactive PDF.
If you want to use a combination of page numbers, insert a space or a comma, type the label, then select another numbering style. The line just below the Custom Page Numbering Format text box shows you how the custom page number will look when you insert it into the document. When you are satisfied with the way the number looks, choose OK. If necessary, choose Set Value to set a new page/chapter/volume number and restart page numbering with the new custom page numbers.
