I ran across this after searching for another posting of mine. (Paul? Do you still work there? You're pretty rude.)

I have no way of confirming that my findings when I (yes) pressed F1 and consulted help - I'm several versions past that one now.

Nevertheless, let's bring up my other, possibly more salient point, which is that Word's renumbering function doesn't work. It hasn't worked since 1992 when I began using the software (were you born yet, Paul?). The Microsoft Word team carries that bug over from one version to the next, and never addresses it. I periodically bring it up on this forum and to Microsoft employees just for grins. I'm now on version 2016, and it's still broken. I've had probably over a dozen updated versions and 27 years of grins!

I'm not talking about renumbering first level numbers - that works. I'm talking SECOND level numbers. If you have several sections in a document, each of which requires a numbered list, you CAN change subsequent lists to "Restart at 1." However, if you have a sub-list of a, b, c, d under a primary list of 1, 2, 3, you CANNOT renumber to "a" in any subsequent lists because the "Restart at a" function hasn't worked at least since 1992. Neither does the function where you display the Numbering Library dialog and replace "e" (or whatever) with "a."

The only solution is to delete the "a" in the numbered sub-list item and TYPE "a" (you're manually numbering this item, in other words) then press Tab. Then you have to reposition the list item to the correct indentation. Then you can press Enter, and the next item will automatically be "b," etc., if you're set to auto-format You have to go through these steps each time you have a subsequent sub-section.
