2. Is there documentation (preferably a tutorial) for this?
You already linked to the relevant documentation: The KatePart Handbook. The
relevant section is "Appendix A. Regular Expressions":
https://docs.kde.org/stable5/en/kate/katepart/regular-expressions.html
Check especially the page on Patterns [0] and the "Capturing matching text (back
references)" paragraph: that paragraph is quoted in your stack overflow link.
I think that is the key/solution to my problem.
You've given me a homework assignment.
Though I worked in Power Supply Engineering in the 70's, I was
surrounded by TECO fanatics. I suspect KATE is as powerful/flexible.
It's rather concise for an examples/tutorial, but I'll an example below.
I wish to write macros using ERE's[1] to make my project feasible.
This is not possible:
Clarification:
I'm unsure of explicitly "This" refers to.
I've extremely little formal computer background -- a 1 semester "intro
to programming" as a freshman engineering student >60 years ago.
I've been a computer _user_ since the days of 12AX7 based CPU's,
Hollerith cards, and network connection via acoustic couplers ;}
I was referring to the general concept of an ERE, not an implementation.
[The Appendix] documents regular expressions in the form available within
KatePart, which is not compatible with the regular expressions of perl, nor
with those of for example grep.

However, I believe that the syntax exposed is very similar and powerful enough.
1. Does that discussion apply to Kate 22.12.3?
Unfortunately I cannot check this definitively since I don't have that version,
but the Kate Handbook is written for Version 22.08, so it should.
For an example of a regex replacement, I assume some basic knowledge about regex
expressions (documentation can be found in the KatePart or elsewhere for similar
regex syntaxes). If things are unclear, feel free to ask.
Replacing the footnotes with uglier but easier clickable items. They were HTML
<sup>[n]</sup> items, but the superscript makes them difficult to click on small
screens. My goal:
Convert
'Then the suitors came in and took their places on the benches and seats.<a href="#linknote-3" id="linknoteref-3" class="pginternal"><sup>[3]</sup></a> Forthwith men'
with
'Then the suitors came in and took their places on the benches and seats.<a href="#linknote-3" id="linknoteref-3" class="pginternal">[3]</a> Forthwith men'
Kate Replace:
<sup>(\[\d+\])</sup> → \1
Explanation: we find all <sup>...</sup> tags, and group the inner contents
with a sub expression. Our replacement text is simply \1, which a reference to
the first sub expression.
