is there a way to perform data form pdf while reading it with OKUKAR (literature-lists) and output it to calc-sheets?
i have heard that i can mark text chunks - if this is possible then i can collect these chunks - and put it to a text file and create csvbased text.
is this possible?

I'm not sure I understand. Selecting chunks and perform a couple of functions on that selection should be there. Text selection is mapped to the right mouse button ( ctrl + F4). However, if you mean select several separated chunks ( like multirow), I'm not sure if it's possible.https://imgur.com/a/uQUT2UU
