BibTeX key generator improvement

It would be nice if an alternative to [shorttitle] could be added which did not exclude “function words”.

I do not know if it is a bug, but the article titled “A few new (?) facts about infinite elements” by Demkowicz in 2006 resolves to “Demkowicz2006fn?” using [auth][year][shorttitle:abbr:lower]. Could it be added an option which ignores words starting with a symbol not being a number or a letter?

It would also be nice if the generator could ignore text between dollar-signs. I.e. “An $\mathcal{O}(1)$ integration scheme for three-dimensional surface scattering problems” by Bruno in 2007, should not give Bruno2007a$1$i (no idea why this is the case) but Bruno2007ais.

Hi,

did you check the option: Enforce legal characters in bibtexkey only in the preferences?
Should be under general, I think. This should discard all illegal characters (e.g. slashes, question marks etc which are not allowed in file systems),

This does nothing for dollar signs unfortunately. Using Jabref 5.0 on Ubuntu.

It seems to me that shorttitleINI has been included as a remedy for this, and this page seems to suggest this option does not ignore function words. However, my newly installed JabRef on Linux still ignores function words, is this a bug?

It should include all words. The descent of become the citation key Tdo in JabRef 5.2–2020-11-26–f1a2fa7. Which title do you use, what result do you get and what result would you expect to get?

My bad, I only got the old version from apt install jabref.
