Hi Bastien and all others Bastien writes: > I tried to implement this: > > http://www.cognition.ens.fr/~guerry/u/bibtex-utils.el That's just WOW!! It will be of much help for many I guess. As soon as it is working. By now, it doesn't work for me. > Try M-x bibtex-make-field-keywords This function produces an empty keywords field at the moment. Something with the function bibtex-collect-keywords-values seems not to work right now. I also tried to run only bibtex-collect-keywords-values, and it just ran for 20 minutes with 100% CPU until I killed the process. So there seems to be a loop somewhere. I reduced my bib-file to some 20 entries for testing purpose. Only some of them contain a keywords-field with just one single keyword. But the same result. Also when I start emacs with -q -nw and load bibtex-utils manually. I send you my bib-file per PM. Please try if it works with this file on your system, so that we can exclude that it is just the file format that produces the problem. > Let me know if this is useful. I will be. I'm sure. Thank you very much. Sven
