My hot Word tip is to use Styles. My other hot Word tip is to use cross-references. If you type "See Figure 3-1" in full, you're doing it wrong.
If anyone from Microsoft is reading this, please fix a) the unreadable text in the Styles drop-down selection list in dark mode and b) stop asking my if the large amount of data I put on the clipboard should be available to other apps when I exit Word. With SSDs, this anachronism takes me far longer to read and click No to vs. just saving the damn clipboard content without asking me.
