A List Style creates a set or group of styles. Word comes with built-in paragraph styles named Heading 1, Heading 2, Heading 3. But there is no connection between them. They just happen to share similar names. A List Style 'groups' those paragraph styles into some order. Only the List Style knows that Heading 1 is followed by Heading 2 and that it is followed by Heading 3. There are 9 levels in any List Style.

Defined lists are often used to track paragraphs for numbering purposes. When you create a paragraph style for numbering, you can assign the style to a defined list, and paragraphs are numbered in that style according to where they appear in the defined list. The first paragraph to appear is given number 1 (“Table 1”), for example, and the next paragraph is given number 2 (“Table 2”), even if it appears several pages later. Because both paragraphs belong to the same defined list, they can be numbered consecutively no matter how far apart they are in the document or book.
GREAT tip with lots of uses! Thank you. This will save me hours of work on some tickets I’m designing. However, I also need to set up table tents that have numbers on them. They’re 2-up, and are folded, so each number needs to appear twice on the same page. In short, I want a page with 1/1 and 2/2, and I’m getting 1/2 and 3/4. Am I missing an obvious fix? Thank you.
Law firms use numbered lists daily to prepare contracts, pleadings, letters and memos. Word makes activating and customizing numbering fairly straightforward. You can create simple numbered lists, such as A, B, C and 1, 2, 3. You can also customize these lists to setup specific numbering styles for your firm and practice group. Multilevel lists such as I, A, 1 are handled through Word's Outline Numbering feature, which is explained later in this chapter. Many firms rely on outline numbered lists to draw up contracts and pleadings. Like numbered lists, outline numbered lists can be customized.
Understanding outline numbering and how outline numbering interacts with styles is crucial to your success in using Word with legal documents. Basic outline numbering can be handled much the same way as bullets and numbering. Seven default outline numbered lists come with Word. Three of the lists format the paragraphs with outline numbers. These lists are in the top row of the dialog box. The remaining four format the paragraphs with outline numbers and apply heading styles to the paragraphs and can be found in the bottom row.

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
