The values for Number position (here called Aligned at), Text indent and Follow number with are in the Position section at the bottom. With multi-level numbering, you also have easy access to settings that control the type of numbering at each level, the characters before and after each level’s numbers (period versus parenthesis), and the list number style (1, a, I, etc.).
Choose the predefined scheme that's most similar to what you want. For instance, if you want sublevels indented, choose the indented form; similarly, if you don't want sublevels indented, choose the flush left form, as shown in Figure C. Try to make the best choice right now because changing your mind later will present so many problems that starting over will be easier.
The above steps are the most basic way to add a very basic page number, but if you follow a few tricks then you could save yourself even more time and get the job done even faster. For one thing, the page number you’ve added is only for one page, and if you used that method you’d spend ages adding page numbers to the whole document. To add page numbers to all pages quickly and format them all equally, follow these steps:
A nested list is a numbered or bulleted list with subordinate (usually indented) numbered or bulleted lists. Rather than just a list of numbered items (1,2,3...), a nested list may have item 1, then indented items numbered a,b,c or i,ii,iii or some other numbering method before the main number 2. With numbering styles you can achieve any combination of numbering formats you want.
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.
The standard method for displaying a page number in InDesign is to insert an Automatic Page Number Marker into a text frame (Text menu: Insert Special Character: Marker: Current Page Number). This is typically done on your master page(s) so that the page number will appear on every page using that master. If you wish to hide the page number on pages in your document, just use a different master that does not include the marker (or use the “None” master if you do not wish to display any master page items).

You may wonder whether typing 1, 2, and 3 would be easier than using the ListNum field. Although doing that may be easier initially, the value of using the ListNum field becomes apparent when you cut and paste. When a paragraph contains multiple numbered items that you move or delete, Word automatically updates the ListNum fields. Using ListNum fields assures you of accurate numbering within a paragraph throughout the document.
1. digit, figure. 2. Number, sum both imply the total of two or more units. Number applies to the result of a count or estimate in which the units are considered as individuals; it is used of groups of persons or things: to have a number of items on the agenda. Sum applies to the result of addition, in which only the total is considered: a large sum of money. 20. copy, edition.
