+Quite a lot of Emacs commands react to the (numeric) prefix. For

+rule of 900 to the current article.
+
+This is all nice and well, but what if you want to give a command some
+additional information? Well, what most commands do is interpret the
+``raw'' prefix in some special way. @kbd{C-u 0 C-x C-s} means that one
+doesn't want a backup file to be created when saving the current buffer,
+for instance. But what if you want to save without making a backup
+file, and you want Emacs to flash lights and play a nice tune at the

+prefixes as you want. @kbd{M-i a M-C-u} means ``feed the @kbd{M-C-u}

+``feed the @kbd{M-C-u} command the symbolic prefixes @code{a} and
+@code{b}''. You get the drift.

+Typing in symbolic prefixes to commands that don't accept them doesn't

+ I like the option for trying to retrieve the FAQ for a group and I was
+thinking it would be great if for those newsgroups that had archives
+you could also try to read the archive for that group. Part of the

+What would be best I suppose is to find the one closest to your site.
+
+In any case, there is a list of general news group archives at @*

+LMI> Well, nnbabyl could alter the group info to heed labels like

+It could also keep them updated (the same for the Status: header of

+
+They could be used like this:
+
+
+@example
+`M l <name> RET' add label <name> to current message.
+`M u <name> RET' remove label <name> from current message.
+`/ l <expr> RET' limit summary buffer according to <expr>.
+
+<expr> would be a boolean expression on the labels, e.g.
+
+`/ l bug & !fixed RET'

+would show all the messages which are labeled `bug' but not labeled

+
+One could also imagine the labels being used for highlighting, or

+I'd like a gnus-find-file which work like find file, except that it
+would recognize things that looks like messages or folders:
+
+- If it is a directory containing numbered files, create an nndir
+summary buffer.
+
+- For other directories, create a nneething summary buffer.
+
+- For files matching "\\`From ", create a nndoc/mbox summary.
+
+- For files matching "\\`BABYL OPTIONS:", create a nndoc/baby summary.
+
+- For files matching "\\`[^ \t\n]+:", create an *Article* buffer.
+
+- For other files, just find them normally.
+
+I'd like `nneething' to use this function, so it would work on a
+directory potentially containing mboxes or babyl files.

+Currently, I get prompted:

+- type y

+
+The problem above is that since there is really only one subsection of
+science, shouldn't it prompt you for only descending sci.something? If
+there was a sci.somethingelse group or section, then it should prompt
+for sci? first the sci.something? then sci.somethingelse?...
+
+@item
+Ja, det burde være en måte å si slikt. Kanskje en ny variabel?

+My precise need here would have been to limit files to Incoming*.
+One could think of some `nneething-only-files' variable, but I guess
+it would have been unacceptable if one was using many unrelated such
+nneething groups.
+
+A more useful approach would be to, in response to the `G D' prompt, be
+allowed to say something like: `~/.mail/Incoming*', somewhat limiting
+the top-level directory only (in case directories would be matched by
+the wildcard expression).

+
+ Take a look at w3-menu.el in the Emacs-W3 distribution - this works out

+article versions) variable.
+
+ So for gnus-summary-menus, I would set to '(sort mark dispose ...)
