I'm too accustomed to traditional MUAs to switch to the "Gnus way" in one= =20 step, so I have: (setq gnus-permanently-visible-groups ".*") (setq gnus-parameters '((".*" (gnus-show-threads nil) (gnus-use-scoring nil) (gnus-article-sort-functions '(gnus-article-sort-by-number)) (display . all)))) I would like to have, in the *Summary*, a complete list of the emails=20 contained in a folder when I hit RET on its label. Each time I do this=20 however, Gnus asks me how many articles I want to retrieve, and issues a=20 "UID FETCH 1:N (UID RFC822.SIZE BODYSTRUCTURE BODY.PEEK[HEADER.FIELDS=20 (...)])" IMAP command, which can take quite some time to complete when N=20 is large. Is there a way to convince Gnus to cache the result of that command=20 (without caching all emails), and to issue a command only for the new=20 UIDs? Caching the result of that command should not eat too much disk=20 space. I apologize in advance if that question is na=EFve, or if I missed some par= t=20 of the manual. Gregory
