One of the easiest ways to begin applying numbers is by starting to type a numbered list. Word recognizes that you are creating a list and responds accordingly by converting text that you type into numbered items. The number scheme, delimiter characters that mark the beginning or end of a unit of data and formatting are all based on what you have typed.

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 next step is to create the simple Excel workbook that contains the ticket numbers. Open a blank Excel sheet. Using Figure B as a guide, create the ticket numbering sheet and save it, making sure to note the new workbook's name and location. As we discussed earlier, the Excel workbook stores the ticket numbers. In this example, we'll create 11 tickets numbered 100 through 110. You'll need to update the ticket values for each merge.
To create a running list—a list that is interrupted by other paragraphs or that spans multiple stories or documents—create a paragraph style and apply the style to paragraphs that you want to be part of the list. For example, to create a running list of the tables in your document, create a paragraph style called Tables, make a defined list part of the style, and then apply the Tables paragraph style to all paragraphs you want in your Table list.
The easiest way to implement a numbering scheme for headings is to add one to a heading style. To illustrate, we'll modify Heading 1 by adding a numbering scheme. First, right-click Heading 1 in the Styles gallery (in the Styles group on the Home tab). Then, choose Modify as shown in Figure A to launch the Modify Style dialog. If you thumb through the default properties, you'll not find a numbering scheme (Figure B). Click the Format button and choose Numbering as shown in Figure B. If necessary, click the Numbering tab. Choose the predefined scheme that's the best match for what you want (Figure C). document numbering in word
