Since Ctrl + S 'ing is so damn handy it would be good to have this functionality when adding or editing a field.
I am quite often making small tweaks then clicking save to then be sent back to the fields overview page. Especially irritating when editing a matrix field block as you have to click on the field, and then drill down through the blocks to find the field you were editing.
Whilst I am here, "Save and add another field" would also be super handy.
We cool though, there's worst things in the world that not having this.
Control + S (and stay where you are) would be nice to have on _any_ page with a Save button IMO :)
@j-greig that should already be the case ;) This request is more about post-shortcut behavior (you should probably be kept on the same page rather than redirected to the parent page).
This has been added for the next release 🎉

Craft 3.5.10 is out now with this.
This would be nice to have on the Entry Type settings page as well!
Added for the next release, as well as for Edit Section pages.
Craft 3.5.17 is out now with the change to Section / Entry Type pages.
