Those shortcuts are my custom settings.

This Tweak can be used to control which fields do not get pasted.

IIRC: when pasting, multiple books can be selected.

Added: The majority of calibre plugins that are published at MR have been developed by users who a) had a need for such a plugin, b) had the wherewithal to develop them… time, skills, etc, and c) were prepared to support the plugins they published.

In recent times users have been using AI (Claude, Gemini, etc) to create plugins, you might want to try that track.

I created a couple plugins for my own use:

CopyToLibrary copies books to another library, overwriting any existing books (matched by identifiers:url); and,
OverwriteBook which overwrites formats and metadata from one book into another in the same library.

The point in both cases is to update/overwrite existing book(s) with new formats/metadata while preserving Calibre's uid/uuid. Neither are complete (no support for 'data files', for example) and cover only the use case I wanted.

I am not interested in polishing, publishing, and supporting these. But if somebody else wants to, they may.
