To include numbering prefixes from higher levels, enter text or click at the start of the Number box and choose Insert Number Placeholder and then select a Level option (for example, Level 1), or enter ^ and then the list level (for example, enter ^1). In a list with first levels numbered 1, 2, 3, and so on, and second levels numbered a, b, c, and so on, including the first-level prefix in the second level renders second-level numbers as 1a, 1b, 1c; 2a, 2b, 2c; 3a, 3b, 3c.
A request for numbering headings in a new document doesn't have to elicit terror—it only sounds ghoulish. If you're good with styles, you might consider a custom numbered list style, but that's too much work. Instead, use Word's built-in heading styles for a painless process. My best advice is to get the numbering scheme in place before you create the document. Trying to number headings in an existing document really can cause nightmares!
We'll work with the existing heading styles. When applying this technique to your own documents, you can modify the heading styles to reflect the properties you need—you're not stuck with the default settings. If, however, the built-in heading styles are already in use because you're working with an existing document, you'll have to create new styles. Avoid this route when possible. We'll be changing properties for the numbering scheme and not the actual heading styles.
You can add a chapter number variable to your document. Like page numbers, chapter numbers can be updated automatically and formatted and styled as text. A chapter number variable is commonly used in documents that are part of a book. A document can have only one chapter number assigned to it; if you want to divide a single document into chapters, you can create sections instead.

One solution is to format the heading with the style and follow it with a hidden paragraph mark. You should format the text in the next paragraph with a style that is not included in the Table of Contents. A hidden paragraph mark keeps the text together on one line when it is printed, even though it is actually two separate paragraphs. The Table of Contents command picks up only those paragraphs with heading styles and places them into the Table of Contents.

My quick process involves setting up a row of plaques with a01, a02, a03, thru a09. Then copy the plaques to the clipboard. Run the REPLACE TEXT feature to replace "a" with "1". Move row down and paste clipboard back into page. Run REPLACE TEXT to replace "a" with "2". Repeat until I get all the numbers. It's faster than manually typing the numbers in but I know there's go to be someway of automating the process.

If you would like the page number placed in a different location, open the Position list box and choose another option. Notice how the preview pages are updated to show you how the page number will look on the printed page. Choose OK to insert the page number code. This code will be automatically updated with the correct page number, no matter how many pages you add or subtract from the document
Every time you save a document in Word, the information in the document properties is updated. Part of the information is a count of how many times the file has been saved. This is referred to as the revision number. You can insert the revision number in your documents and have it updated automatically, if you so desire. To insert the revision number in your document, follow these steps:
In records containing punctuation, enclose data in a single occurrence of subfield ǂq in parentheses. Enclose data in multiple occurrences of subfield ǂq in one set of parentheses and separate individual occurrences of subfield ǂq with a space, semicolon, space. Omit any punctuation from the end of the field unless it ends with an ellipsis, hyphen, closing parenthesis, exclamation point, question mark, or period following an abbreviation.
This chapter (web page) takes you through how numbering is supposed to work in Word and the various controls. It is useful, but primarily on SEQ fields and simple numbered lists and also as reference showing the menus, dialogs and controls and going through the concepts for outline numbering. To actually set up outline numbering that works, refer to the Kelly and McGhie articles.
