I’ve got an outline numbering scheme where the first 4 levels are 1, 1.1, 1.1.1 and (a). The 4th level — (a) — sometimes ends up being used for substantive text paragraphs and sometimes for lists of short items (less than one line long). In the former case I want spacing between paragraphs, and in the latter case not.
As an experiment, I just created a totally clean new document based on the Word 2002 default (straight out of the box) Normal template. Then I fastidiously set up a 9-level outline numbering scheme linked to the 9 Heading styles in the famous how-to-stay-out-of-trouble fashion. When I’d finished, I confirmed that the document had one (and only one) List Template.
Here’s the twist: Then I created a new style — which I called Heading 4 SS — which is “Based on” Heading 4, and with the only difference with Heading 4 being that I checked “Don’t add space between paragraphs of the same style” under Paragraph Format for Heading 4 SS. (In creating Heading 4 SS, I did not visit the Numbering dialog.) Then I re-checked the document’s List Template count and it still had only one List Template, meaning that (as I’d hoped) Heading 4 SS is linked to the same List Template as Heading 4 (and the other 8 built-in Heading styles).
I then tried formatting a series of paragraphs and the numbering scheme works exactly as intended.
My question is this: Notwithstanding that everything is working fine now, does the fact that I have 2 different styles linked to the 4th level of the same List Template mean that I’m working with an unstable structure that is reasonably likely to act up at some point? Or am I probably safe (1) given that my 2nd link to the 4th level of the List Template is the indirect result of a “Based on” link to the directly-linked style and (2) assuming that I never independently modify the numbering formatting for the 2nd 4th-level style (i.e., assuming any change I ever make to level 4 of the List Template results from “digging to China” with the cursor in a Heading 1 paragraph)?
An alternative, of course, would be to dispense with Heading 4 SS and simply implement the “Don’t add space between paragraphs of the same style” formatting as direct formatting when needed. But I understand that the recommended Word approach (I’m a newbie) is to minimize the use of direct formatting, so I thought the alternative-style approach might be the way to go.
