"%documentLink%" in comments field not supported?

Thank you for the quick clarification.

Basically, my attempt here is a workaround: I want to copy markdown formatted information to the clipboard to be able to paste it into another program - for reference.

I tried to have the info written in the comments to be able to copy it by hand, but now the Item link will be missing.

I am sure with a script it is much more elegant, easier and faster. I have seen something similar in the forum: Markdown version of the Item link

But unfortunately I don’t know anything about coding at all. I know what a script is, may able to change a value – thats it.

Maybe someone can help me out: What values would I have to enter in the script mentioned? To become a result in the clipboard like this:

[>document name<] (>ItemLink<)
recived: >CreationDate<
from: [>ItemAuthors<] (mailto:>AuthorEmailAddresses<)

the DT placeholder for this should be:
%documentLink%
%recordCreationShortDate%
%kMDItemAuthors%%kMDItemAuthorEmailAddresses%
