I suppose your average user (on either interface) won’t know MARC anyway…
I know a Marc, he is a friend of mine ^^

Hi all!
For what it's worth, there is a list of Zebra indexes in the manual: 
https://koha-community.org/manual/latest/en/html/searching.html#koha-search-... 
<https://koha-community.org/manual/latest/en/html/searching.html#koha-search-indexes>. 
I'm all for a fun tool that shows them within Koha, but it'd also be 
great if the manual were up to date.
Speaking of showing search indexes right in the Koha staff client, 
Elastic already does that. The Search Engine Config page in 
administration shows you exactly how all of your MARC data is indexed 
for Elastic. It would totally make sense to rework this to also be able 
to show Zebra values.

Hi, sounds nice.
FIY I am actually using a transformation of Zebra config in order to
    present it in CSV:
    https://git.biblibre.com/biblibre/tools/src/branch/master/zebra/list_indexes...
    <https://git.biblibre.com/biblibre/tools/src/branch/master/zebra/list_indexes.xsl>
We may use this to display in HTML.
Best regards,
