So now on the A master page in your Adobe InDesign document you should have a capital A in the text frame that we created. This is more than just a capital A though, this represents the A master in your Adobe Indesign document and it means that on every page that is attached to your A master the corresponding page number will appear in that position on your page.
Notice that the Font option (when you applied italics) changes only the number, not the heading text. To update the heading text, modify the heading style as you normally would. Word assumes you want all Heading 1 and Heading 2 styles included in the new numbering scheme. If you want to omit a heading level from the scheme, don't use a built-in heading style to format those headings.
Some drawbacks to this feature are that you lose a little control when you are typing. Word formats for you and some users do not like this. Also, on certain items, you will get a number when you do not expect or need one. For example, you have an attorney whose name begins with an initial (A. George Smith). When you type the name and press ENTER, the first initial "A." converts to an automatic number.
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).
To modify the options, click the Multilevel List option (in the Paragraph Group). Word selects all lists currently in use in the List Library. You'll see two options below the gallery: Define New Multilevel List and Define New List Style. Use the first to create and save a stable custom list style. You'll use the second to change list styles. You can also use the latter to create a new style. So, what's the difference? The Define New List Style option lets you name a style, so you can share, modify, and delete it later. Most users will never need this option. Now, let's move on: choose Define New Multilevel List. Figure D shows the resulting dialog.
Changing the numbering display affects how pages are indicated in the InDesign document, as in the Pages panel and in the page box at the bottom of a document window. The numbering display also affects how you specify page ranges when printing and exporting the document. However, the numbering display does not change the appearance of page numbers on document pages. numbering in indesign
