JabRef should, if necessary, warn about changes to the "citationkeys" that have been added to the files!

[NeymanDmitry]

The directory marked as "Latex file directory" contains many documents that can be linked to the library through existing citationkeys.

A simple change in the rules of citatiokey formation in the program leads to the loss of relevant links in the relevant TeX documents.

So you might have to fix hundreds of links manually!?

Suggestion for improvement:

Each time the citation key is changed, it is necessary to automatically check whether this citationkeys are included in the documents corresponding to the Latex file directory. If they are included, there should be at least two possibilities to change the citationkeys data in the documents, the default action and rename automatically.

I never thought about a usage like this. Normally, files are linked in directories configured elsewhere. See https://docs.jabref.org/finding-sorting-and-cleaning-entries/filelinks.

I wonder whether one implicit issue here is the question of whether JabRef should offer to rename a file, when the link to the linked file is affected by the change of the respective entry's data (such as author, citationkey, year, etc).

I think at the moment, JabRef only links to files; but does not track whether a file should be renamed. For the latter, see #11316

I'm sorry for my English! I meant that when citationkey changes in the JabRef program, it is necessary to include the changes in the corresponding \cite{...} from the TeX documents.

For example, if you change citationkey1 to citationkey2 in the entry table, then you must automatically replace \cite{citationkey1} with \cite{citationkey2} in the TeX document (the article may be).
