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.
If you start to type in what appears to be a numbered list, Word formats your manually typed "numbers" to an automatic numbered list. The main benefit of this option is that you do not need to click any button to start numbering and you can choose your numbering style as well. For example, if you type "(a) some text" and press Enter, it starts numbering using the "(a)" format.

It sure is possible! Numbering and Section options are available in the Pages Panel menu. These options allow you to define what page starts a section and how it should be numbered. Insert a Current Page Number marker (Type>Insert Special Character>Markers>Current Page Number) in a text frame on a page or master page (recommended), select the first page of your section, open the Numbering and Section Options dialog, and enter 200 in the Start Page Numbering at: field. Hope this helps!

If you’re a self-taught InDesign user, you may not have been introduced to automatic page numbering, one of the biggest time-saving features in the program. InDesign allows you to set up the page numbering feature in your Master Pages. Then, as you add or shuffle pages, InDesign updates individual page numbers accordingly. You can style the page number any way you like.

Let's say you just created a paragraph in Heading 1 style. Now, you press Enter to go on to create the next paragraph. What style will that paragraph be in? You can modify a style to stipulate the style Word uses for the following paragraph. So you could set it up so that, when you're entering text, a Heading 1 will be followed by a Heading 2. And, you could set it up so that a paragraph in Heading 2 will be followed by a paragraph in style Body Text.
c.1300, "sum, aggregate of a collection," from Anglo-French noumbre, Old French nombre and directly from Latin numerus "a number, quantity," from PIE root *nem- "to divide, distribute, allot" (related to Greek nemein "to deal out;" see nemesis). Meaning "symbol or figure of arithmatic value" is from late 14c. Meaning "single (numbered) issue of a magazine" is from 1795. The meaning "musical selection" (1885) is from vaudeville theater programs, where acts were marked by a number. Meaning "dialing combination to reach a particular telephone receiver" is from 1879; hence wrong number (1886).
