Helpful git tips

This is a discussion.

I'm wondering what git commands or use patterns you have found helpful or needed to look up frequently while working on the docs, but which aren't covered currently.

(I don't want to duplicate git documentation, but some advice MIGHT be helpful.)

I'll start by mentioning a few...

No file, test, or entry point is named. Start by reviewing the existing Git guidance in this Sphinx documentation project and the discussion's proposed commands or patterns. Done would require a decided, non-duplicative scope before any documentation change is made.
