A List Style stores the information about how to number each level. That includes the format of the number ( "1" or "a" or "i"), whether the number is preceded by text (eg "Chapter 1" or "Part A"), whether the number includes previous levels' numbers (eg paragraph 1.4.3), and the indents (the distance from margin to number and from number to text).
See Word's Numbering Explained by John McGhie, MVP - comprehensive and not pretty (Downloadable pdf file in letter size) - Reading this is vital to anyone attempting to use automatic numbering or bullets in a law office setting or other places where the documents are likely to be reused or heavily edited. See also How to Create a Template with a downloadable template with style-based numbering.
When you are ready to restart numbering, you can use the technique above, or you can place your cursor inside a numbered paragraph above, click the Format Painter (the paintbrush icon on the Home tab under Clipboard), then click on the line where you want to restart numbering. Using Format Painter this way solves several paragraph numbering problems (the number sequence, indents, and inter-paragraph spacing) simultaneously.
UPDATE: I was able to fix this by DEselecting “Allow Document Pages to Shuffle” and “Allow Spreads to Shuffle.” Or perhaps I only need to do one of those, but I was trying everything in the book and happen to uncheck those. Once I deselected those, I was able to move the spreads back to the way they needed to be. Of course, I had to do each of them individually, which would be tedious if you had a very large document already created. Definitely something that I will have to remember to do at the beginning of creating a document. (Luckily, this particular one is only six pages.) I’m wondering if there is a quicker way if this issue returned.
Many Office programs will detect when you start a numbered or bulleted list and helpfully automate it, so that when you press Enter, new list items are automatically indented and bulleted or numbered. If this behavior isn’t actually all that helpful for you, and you’d rather control your own list-making without Office’s help, you can turn to your autocorrect options.
This feature is easiest to use when you combine it with Word's built-in heading styles. However, you can map a custom heading style to the multilevel numbering feature—it just takes more work. Word handles nine levels, but any document with more than four levels should receive a serious developmental edit. More than four becomes confusing and perhaps worse, unreadable.
A quick way to create a bulleted or numbered list is to type the list, select it, and then click the Bulleted List or Numbered List button in the Control panel. These buttons let you turn the list on or off and switch between bullets and numbers. You can also make bullets and numbering part of a paragraph style and construct lists by assigning styles to paragraphs.

Drag the number, which Publisher defaults to “1,” into place on the ticket. To change the sequence, such as to start with “100” instead of “1,” click the “Page Number” button again and choose “Format Page Numbers.” Click the “Start this section with” radio button and type the new number into the field. Click the “OK” button to have Publisher update the ticket number. numbering using indesign
