Sorting Groups
==============
The `C-c C-s' (`gnus-group-sort-groups') command sorts the group
buffer according to the function(s) given by the
`gnus-group-sort-function' variable. Available sorting functions
include:
`gnus-group-sort-by-alphabet'
Sort the group names alphabetically. This is the default.
`gnus-group-sort-by-level'
Sort by group level.
`gnus-group-sort-by-score'
Sort by group score.
`gnus-group-sort-by-rank'
Sort by group score and then the group level. The level and the
score are, when taken together, the group's "rank".
`gnus-group-sort-by-unread'
Sort by number of unread articles.
`gnus-group-sort-by-method'
Sort by alphabetically on the select method.
`gnus-group-sort-function' can also be a list of sorting functions.
In that case, the most significant sort key function must be the last
There are also a number of commands for sorting directly according to
some sorting criteria:
`G S a'
Sort the group buffer alphabetically by group name
(`gnus-group-sort-groups-by-alphabet').
`G S u'
Sort the group buffer by the number of unread articles
(`gnus-group-sort-groups-by-unread').
`G S l'
Sort the group buffer by group level
(`gnus-group-sort-groups-by-level').
`G S v'
Sort the group buffer by group score
(`gnus-group-sort-groups-by-score').
`G S r'
Sort the group buffer by group level
(`gnus-group-sort-groups-by-rank').
`G S m'
Sort the group buffer alphabetically by backend name
(`gnus-group-sort-groups-by-method').
When given a prefix, all these commands will sort in reverse order.
File: gnus, Node: Group Maintenance, Next: Browse Foreign Server, Prev: Sorting Groups, Up: The Group Buffer
Group Maintenance
=================
Find bogus groups and delete them
(`gnus-group-check-bogus-groups').
Find new groups and process them (`gnus-find-new-newsgroups'). If
given a prefix, use the `ask-server' method to query the server for
new groups.
`C-c C-x'
Run all expirable articles in the current group through the expiry
process (if any) (`gnus-group-expire-articles').
`C-c M-C-x'
Run all articles in all groups through the expiry process
(`gnus-group-expire-all-groups').
File: gnus, Node: Browse Foreign Server, Next: Exiting Gnus, Prev: Group Maintenance, Up: The Group Buffer
Browse Foreign Server
=====================
You will be queried for a select method and a server name. Gnus
will then attempt to contact this server and let you browse the
groups there (`gnus-group-browse-foreign-server').
A new buffer with a list of available groups will appear. This
buffer will be use the `gnus-browse-mode'. This buffer looks a bit
(well, a lot) like a normal group buffer, but with one major difference
- you can't enter any of the groups. If you want to read any of the
news available on that server, you have to subscribe to the groups you
think may be interesting, and then you have to exit this buffer. The
new groups will be added to the group buffer, and then you can read them
as you would any other group.
Future versions of Gnus may possibly permit reading groups straight
from the browse buffer.
Here's a list of keystrokes available in the browse mode:
Go to the next group (`gnus-group-next-group').
Go to the previous group (`gnus-group-prev-group').
`SPACE'
Enter the current group and display the first article
(`gnus-browse-read-group').
`RET'
Enter the current group (`gnus-browse-select-group').
Unsubscribe to the current group, or, as will be the case here,
subscribe to it (`gnus-browse-unsubscribe-current-group').
Exit browse mode (`gnus-browse-exit').
Describe browse mode briefly (well, there's not much to describe,
is there) (`gnus-browse-describe-briefly').
File: gnus, Node: Exiting Gnus, Next: Group Topics, Prev: Browse Foreign Server, Up: The Group Buffer
Exiting Gnus
============
Yes, Gnus is ex(c)iting.
Suspend Gnus (`gnus-group-suspend'). This doesn't really exit
Gnus, but it kills all buffers except the Group buffer. I'm not
sure why this is a gain, but then who am I to judge?
Quit Gnus (`gnus-group-exit').
Quit Gnus without saving any startup files (`gnus-group-quit').
`gnus-suspend-gnus-hook' is called when you suspend Gnus and
`gnus-exit-gnus-hook' is called when you quit Gnus, while
`gnus-after-exiting-gnus-hook' is called as the final item when exiting
Gnus.
If you wish to completely unload Gnus and all its adherents, you can
use the `gnus-unload' command. This command is also very handy when
trying to customize meta-variables.
Note:
Miss Lisa Cannifax, while sitting in English class, feels her feet
go numbly heavy and herself fall into a hazy trance as the boy
sitting behind her drew repeated lines with his pencil across the
back of her plastic chair.
File: gnus, Node: Group Topics, Next: Misc Group Stuff, Prev: Exiting Gnus, Up: The Group Buffer
Group Topics
============
If you read lots and lots of groups, it might be convenient to group
them hierarchically according to topics. You put your Emacs groups over
here, your sex groups over there, and the rest (what, two groups or so?)
you put in some misc section that you never bother with anyway. You can
even group the Emacs sex groups as a sub-topic to either the Emacs
groups or the sex groups--or both! Go wild!
To get this *fab* functionality you simply turn on (ooh!) the
`gnus-topic' minor mode--type `t' in the group buffer. (This is a
toggling command.)
Go ahead, just try it. I'll still be here when you get back. La de
dum... Nice tune, that... la la la... What, you're back? Yes, and now
press `l'. There. All your groups are now listed under `misc'.
Doesn't that make you feel all warm and fuzzy? Hot and bothered?
If you want this permanently enabled, you should add that minor mode
to the hook for the group mode:
(add-hook 'gnus-group-mode-hook 'gnus-topic-mode)
* Menu:
* Topic Variables:: How to customize the topics the Lisp Way.
* Topic Commands:: Interactive E-Z commands.
* Topic Topology:: A map of the world.
File: gnus, Node: Topic Variables, Next: Topic Commands, Up: Group Topics
Topic Variables
---------------
Now, if you select a topic, if will fold/unfold that topic, which is
really neat, I think.
The topic lines themselves are created according to the
`gnus-topic-line-format' variable. *Note Formatting Variables::.
Elements allowed are:
Indentation.
Topic name.
Visibility.
Level.
Number of groups in the topic.
Number of unread articles in the topic.
Number of unread articles in the topic and all its subtopics.
Each sub-topic (and the groups in the sub-topics) will be indented
with `gnus-topic-indent-level' times the topic level number of spaces.
The default is `2'.
`gnus-topic-mode-hook' is called in topic minor mode buffers.
File: gnus, Node: Topic Commands, Next: Topic Topology, Prev: Topic Variables, Up: Group Topics
Topic Commands
--------------
When the topic minor mode is turned on, a new `T' submap will be
available. In addition, a few of the standard keys change their
definitions slightly.
`T n'
Prompt for a new topic name and create it
(`gnus-topic-create-topic').
`T m'
Move the current group to some other topic
(`gnus-topic-move-group'). This command understands the
process/prefix convention (*note Process/Prefix::.).
`T c'
Copy the current group to some other topic
(`gnus-topic-copy-group'). This command understands the
process/prefix convention (*note Process/Prefix::.).
`T D'
Remove a group from the current topic (`gnus-topic-remove-group').
This command understands the process/prefix convention (*note
Process/Prefix::.).
`T M'
Move all groups that match some regular expression to a topic
(`gnus-topic-move-matching').
`T C'
Copy all groups that match some regular expression to a topic
(`gnus-topic-copy-matching').
`T #'
Mark all groups in the current topic with the process mark
(`gnus-topic-mark-topic').
`T M-#'
Remove the process mark from all groups in the current topic
(`gnus-topic-unmark-topic').
`RET'
`SPACE'
Either select a group or fold a topic (`gnus-topic-select-group').
When you perform this command on a group, you'll enter the group,
as usual. When done on a topic line, the topic will be folded (if
it was visible) or unfolded (if it was folded already). So it's
basically a toggling command on topics. In addition, if you give
a numerical prefix, group on that level (and lower) will be
displayed.
`T TAB'
"Indent" the current topic so that it becomes a sub-topic of the
previous topic (`gnus-topic-indent'). If given a prefix,
"un-indent" the topic instead.
`C-k'
Kill a group or topic (`gnus-topic-kill-group').
`C-y'
Yank the previously killed group or topic
(`gnus-topic-yank-group'). Note that all topics will be yanked
before all groups.
`T r'
Rename a topic (`gnus-topic-rename').
`T DEL'
Delete an empty topic (`gnus-topic-delete').
`A T'
List all groups that Gnus knows about in a topics-ified way
(`gnus-topic-list-active').
File: gnus, Node: Topic Topology, Prev: Topic Commands, Up: Group Topics
Topic Topology
--------------
So, let's have a look at an example group buffer:
Gnus
Emacs -- I wuw it!
3: comp.emacs
2: alt.religion.emacs
Naughty Emacs
452: alt.sex.emacs
0: comp.talk.emacs.recovery
Misc
8: comp.binaries.fractals
13: comp.sources.unix
So, here we have one top-level topic, two topics under that, and one
sub-topic under one of the sub-topics. (There is always just one (1)
top-level topic). This topology can be expressed as follows:
(("Gnus" visible)
(("Emacs -- I wuw it!" visible)
(("Naughty Emacs" visible)))
(("Misc" visible)))
This is in fact how the variable `gnus-topic-topology' would look
for the display above. That variable is saved in the `.newsrc.eld'
file, and shouldn't be messed with manually--unless you really want to.
Since this variable is read from the `.newsrc.eld' file, setting it in
any other startup files will have no effect.
This topology shows what topics are sub-topics of what topics
(right), and which topics are visible. Two settings are currently
allowed--`visible' and `invisible'.

Misc Group Stuff
================
* Menu:
* Scanning New Messages:: Asking Gnus to see whether new messages have arrived.
* Group Information:: Information and help on groups and Gnus.
* File Commands:: Reading and writing the Gnus files.
Enter the server buffer (`gnus-group-enter-server-mode'). *Note
The Server Buffer::.
Post an article to a group (`gnus-group-post-news'). The current
group name will be used as the default.
Mail a message somewhere (`gnus-group-mail').
Variables for the group buffer:
`gnus-group-mode-hook'
`gnus-group-mode-hook' is called after the group buffer has been
created.
`gnus-group-prepare-hook'
`gnus-group-prepare-hook' is called after the group buffer is
generated. It may be used to modify the buffer in some strange,
unnatural way.
`gnus-permanently-visible-groups'
Groups matching this regexp will always be listed in the group
buffer, whether they are empty or not.
File: gnus, Node: Scanning New Messages, Next: Group Information, Up: Misc Group Stuff
Scanning New Messages
---------------------
Check the server(s) for new articles. If the numerical prefix is
used, this command will check only groups of level ARG and lower
(`gnus-group-get-new-news'). If given a non-numerical prefix, this
command will force a total rereading of the active file(s) from the
backend(s).
`M-g'
Check whether new articles have arrived in the current group
(`gnus-group-get-new-news-this-group'). The
`gnus-goto-next-group-when-activating' variable controls whether
this command is to move point to the next group or not. It is `t'
by default.
`C-c M-g'
Activate absolutely all groups (`gnus-activate-all-groups').
Restart Gnus (`gnus-group-restart').
`gnus-get-new-news-hook' is run just before checking for new news.
`gnus-after-getting-new-news-hook' is run after checking for new
news.
File: gnus, Node: Group Information, Next: File Commands, Prev: Scanning New Messages, Up: Misc Group Stuff
Group Information
-----------------
`M-f'
Try to fetch the FAQ for the current group
(`gnus-group-fetch-faq'). Gnus will try to get the FAQ from
`gnus-group-faq-directory', which is usually a directory on a
remote machine. `ange-ftp' will be used for fetching the file.
Describe the current group (`gnus-group-describe-group'). If given
a prefix, force Gnus to re-read the description from the server.
`M-d'
Describe all groups (`gnus-group-describe-all-groups'). If given a
prefix, force Gnus to re-read the description file from the server.
Display current Gnus version numbers (`gnus-version').
Give a very short help message (`gnus-group-describe-briefly').
`C-c C-i'
Go to the Gnus info node (`gnus-info-find-node').
File: gnus, Node: File Commands, Prev: Group Information, Up: Misc Group Stuff
File Commands
-------------
Read the init file (`gnus-init-file', which defaults to `~/.gnus')
(`gnus-group-read-init-file').
Save the `.newsrc.eld' file (and `.newsrc' if wanted)
(`gnus-group-save-newsrc'). If given a prefix, force saving the
file(s) whether Gnus thinks it is necessary or not.

Gnus will use the value of the `gnus-extract-address-components'
variable as a function for getting the name and address parts of a
`From' header. Two pre-defined function exist:
`gnus-extract-address-components', which is the default, quite fast,
and too simplistic solution; and `mail-extract-address-components',
which works very nicely, but is slower. The default function will
return the wrong answer in 5% of the cases. If this is unacceptable to
you, use the other function instead.
`gnus-summary-same-subject' is a string indicating that the current
article has the same subject as the previous. This string will be used
with those specs that require it. The default is `'.
File: gnus, Node: Summary Buffer Lines, Next: Summary Buffer Mode Line, Up: Summary Buffer Format
Summary Buffer Lines
--------------------
You can change the format of the lines in the summary buffer by
changing the `gnus-summary-line-format' variable. It works along the
same lines a a normal `format' string, with some extensions.
The default string is `%U%R%z%I%(%[%4L: %-20,20n%]%) %s\n'.
The following format specification characters are understood:
Article number.
Subject string.
Subject if the article is the root, `gnus-summary-same-subject'
otherwise.
Full `From' line.
The name (from the `From' header).
The name (from the `From' header). This differs from the `n' spec
in that it uses `gnus-extract-address-components', which is
slower, but may be more thorough.
The address (from the `From' header). This works the same way as
the `a' spec.
Number of lines in the article.
Number of characters in the article.
Indentation based on thread level (*note Customizing Threading::.).
Nothing if the article is a root and lots of spaces if it isn't (it
pushes everything after it off the screen).
Opening bracket, which is normally `\[', but can also be `<' for
adopted articles.
Closing bracket, which is normally `\]', but can also be `>' for
adopted articles.
One space for each thread level.
Twenty minus thread level spaces.
Unread.
Replied.
Score as a number.
Zcore, `+' if above the default level and `-' if below the default
level. If the difference between `gnus-summary-default-level' and
the score is less than `gnus-summary-zcore-fuzz', this spec will
not be used.
Total thread score.
`Xref'.
`Date'.
`Message-ID'.
`References'.
Number of articles in the current sub-thread. Using this spec
will slow down summary buffer generation somewhat.
A single character will be displayed if the article has any
children.
User defined specifier. The next character in the format string
should be a letter. GNUS will call the function
`gnus-user-format-function-'`X', where `X' is the letter following
`%u'. The function will be passed the current header as argument.
The function should return a string, which will be inserted into
the summary just like information from any other summary specifier.
The `%U' (status), `%R' (replied) and `%z' (zcore) specs have to be
handled with care. For reasons of efficiency, Gnus will compute what
column these characters will end up in, and "hard-code" that. This
means that it is illegal to have these specs after a variable-length
spec. Well, you might not be arrested, but your summary buffer will
look strange, which is bad enough.
The smart choice is to have these specs as far to the left as
possible. (Isn't that the case with everything, though? But I
digress.)
This restriction may disappear in later versions of Gnus.
File: gnus, Node: Summary Buffer Mode Line, Next: Summary Highlighting, Prev: Summary Buffer Lines, Up: Summary Buffer Format
Summary Buffer Mode Line
------------------------
You can also change the format of the summary mode bar. Set
`gnus-summary-mode-line-format' to whatever you like. Here are the
elements you can play with:
Group name.
Unprefixed group name.
Current article number.
Gnus version.
Number of unread articles in this group.
Number of unselected articles in this group.
A string with the number of unread and unselected articles
represented either as `<%U(+%u) more>' if there are both unread
and unselected articles, and just as `<%U more>' if there are just
unread articles and no unselected ones.
Shortish group name. For instance, `rec.arts.anime' will be
shortened to `r.a.anime'.
Subject of the current article.
Used-defined spec.
Name of the current score file.
Number of dormant articles.
Number of ticked articles.
Number of articles that have been marked as read in this session.
Number of articles expunged by the score files.
File: gnus, Node: Summary Highlighting, Prev: Summary Buffer Mode Line, Up: Summary Buffer Format
Summary Highlighting
--------------------
`gnus-visual-mark-article-hook'
This hook is run after selecting an article. It is meant to be
used for highlighting the article in some way. It is not run if
`gnus-visual' is `nil'.
`gnus-summary-update-hook'
This hook is called when a summary line is changed. It is not run
if `gnus-visual' is `nil'.
`gnus-summary-selected-face'
This is the face (or "font" as some people call it) that is used to
highlight the current article in the summary buffer.
`gnus-summary-highlight'
Summary lines are highlighted according to this variable, which is
a list where the elements are on the format `(FORM . FACE)'. If
you would, for instance, like ticked articles to be italic and
high-scored articles to be bold, you could set this variable to
something like
(((eq mark gnus-ticked-mark) . italic)
((> score default) . bold))
As you may have guessed, if FORM returns a non-`nil' value, FACE
will be applied to the line.
File: gnus, Node: Summary Maneuvering, Next: Choosing Articles, Prev: Summary Buffer Format, Up: The Summary Buffer
Summary Maneuvering
===================
All the straight movement commands understand the numeric prefix and
behave pretty much as you'd expect.
None of these commands select articles.
`G M-n'
`M-n'
Go to the next summary line of an unread article
(`gnus-summary-next-unread-subject').
`G M-p'
`M-p'
Go to the previous summary line of an unread article
(`gnus-summary-prev-unread-subject').
`G j'
Ask for an article number and then go that article
(`gnus-summary-goto-article').
`G g'
Ask for an article number and then go the summary line of that
article (`gnus-summary-goto-subject').
If Gnus asks you to press a key to confirm going to the next group,
you can use the `C-n' and `C-p' keys to move around the group buffer,
searching for the next group to read without actually returning to the
group buffer.
Variables related to summary movement:
`gnus-auto-select-next'
If you are at the end of the group and issue one of the movement
commands, Gnus will offer to go to the next group. If this
variable is `t' and the next group is empty, Gnus will exit
summary mode and return to the group buffer. If this variable is
neither `t' nor `nil', Gnus will select the next group, no matter
whether it has any unread articles or not. As a special case, if
this variable is `quietly', Gnus will select the next group
without asking for confirmation. If this variable is
`almost-quietly', the same will happen only if you are located on
the last article in the group. Finally, if this variable is
`slightly-quietly', the `Z n' command will go to the next group
without confirmation. Also *note Group Levels::..
`gnus-auto-select-same'
If non-`nil', all the movement commands will try to go to the next
article with the same subject as the current. This variable is not
particularly useful if you use a threaded display.
`gnus-summary-check-current'
If non-`nil', all the "unread" movement commands will not proceed
to the next (or previous) article if the current article is unread.
Instead, they will choose the current article.
`gnus-auto-center-summary'
If non-`nil', Gnus will keep the point in the summary buffer
centered at all times. This makes things quite tidy, but if you
have a slow network connection, or simply do not like this
un-Emacsism, you can set this variable to `nil' to get the normal
Emacs scrolling action. This will also inhibit horizontal
re-centering of the summary buffer, which might make it more
inconvenient to read extremely long threads.
File: gnus, Node: Choosing Articles, Next: Paging the Article, Prev: Summary Maneuvering, Up: The Summary Buffer
Choosing Articles
=================
None of the following movement commands understand the numeric
prefix, and they all select and display an article.
`SPACE'
Select the current article, or, if that one's read already, the
next unread article (`gnus-summary-next-page').
`G n'
Go to next unread article (`gnus-summary-next-unread-article').
`G p'
Go to previous unread article (`gnus-summary-prev-unread-article').
`G N'
Go to the next article (`gnus-summary-next-article').
`G P'
Go to the previous article (`gnus-summary-prev-article').
`G C-n'
Go to the next article with the same subject
(`gnus-summary-next-same-subject').
`G C-p'
Go to the previous article with the same subject
(`gnus-summary-prev-same-subject').
`G f'
Go to the first unread article
(`gnus-summary-first-unread-article').
`G b'
Go to the article with the highest score
(`gnus-summary-best-unread-article').
`G l'
Go to the previous article read (`gnus-summary-goto-last-article').
`G p'
Pop an article off the summary history and go to this article
(`gnus-summary-pop-article'). This command differs from the
command above in that you can pop as many previous articles off the
history as you like.
Some variables that are relevant for moving and selecting articles:
`gnus-auto-extend-newsgroup'
All the movement commands will try to go to the previous (or next)
article, even if that article isn't displayed in the Summary
buffer if this variable is non-`nil'. Gnus will then fetch the
article from the server and display it in the article buffer.
`gnus-select-article-hook'
This hook is called whenever an article is selected. By default it
exposes any threads hidden under the selected article.
`gnus-mark-article-hook'
This hook is called whenever an article is selected. It is
intended to be used for marking articles as read. The default
value is `gnus-summary-mark-read-and-unread-as-read', and will
change the mark of almost any article you read to
`gnus-unread-mark'. The only articles not affected by this
function are ticked, dormant, and expirable articles. If you'd
instead like to just have unread articles marked as read, you can
use `gnus-summary-mark-unread-as-read' instead. It will leave
marks like `gnus-low-score-mark', `gnus-del-mark' (and so on)
alone.
File: gnus, Node: Paging the Article, Next: Reply Followup and Post, Prev: Choosing Articles, Up: The Summary Buffer
Scrolling the Article
=====================
`SPACE'
Pressing `SPACE' will scroll the current article forward one page,
or, if you have come to the end of the current article, will
choose the next article (`gnus-summary-next-page').
`DEL'
Scroll the current article back one page
(`gnus-summary-prev-page').
`RET'
Scroll the current article one line forward
(`gnus-summary-scroll-up').
`A g'
(Re)fetch the current article (`gnus-summary-show-article'). If
given a prefix, fetch the current article, but don't run any of the
article treatment functions. This will give you a "raw" article,
just the way it came from the server.
`A <'
Scroll to the beginning of the article
(`gnus-summary-beginning-of-article').
`A >'
Scroll to the end of the article (`gnus-summary-end-of-article').
`A s'
Perform an isearch in the article buffer
(`gnus-summary-isearch-article').

(`gnus-summary-reply').
`S R'
Mail a reply to the author of the current article and include the
original message (`gnus-summary-reply-with-original'). This
command uses the process/prefix convention.
`S o m'
Forward the current article to some other person
(`gnus-summary-mail-forward').
`S o p'
Forward the current article to a newsgroup
(`gnus-summary-post-forward').
`S m'
Send a mail to some other person
(`gnus-summary-mail-other-window').
`S D b'
If you have sent a mail, but the mail was bounced back to you for
some reason (wrong address, transient failure), you can use this
command to resend that bounced mail
(`gnus-summary-resend-bounced-mail'). You will be popped into a
mail buffer where you can edit the headers before sending the mail
off again. If you give a prefix to this command, and the bounced
mail is a reply to some other mail, Gnus will try to fetch that
mail and display it for easy perusal of its headers. This might
very well fail, though.
`S D r'
Not to be confused with the previous command,
`gnus-summary-resend-message' will prompt you for an address to
send the current message off to, and then send it to that place.
The headers of the message won't be altered--but lots of headers
that say `Resent-To', `Resent-From' and so on will be added. This
means that you actually send a mail to someone that has a `To'
header that (probably) points to yourself. This will confuse
people. So, natcherly you'll only do that if you're really eVIl.
This command is mainly used if you have several accounts and want
to ship a mail to a different account of yours. (If you're both
`root' and `postmaster' and get a mail for `postmaster' to the
`root' account, you may want to resend it to `postmaster'.
Ordnung muss sein!
`S O m'
Digest the current series and forward the result using mail
(`gnus-uu-digest-mail-forward'). This command uses the
process/prefix convention (*note Process/Prefix::.).
`S O p'
Digest the current series and forward the result to a newsgroup
(`gnus-uu-digest-mail-forward').

Canceling Articles
==================
Have you ever written something, and then decided that you really,
really, really wish you hadn't posted that?
Well, you can't cancel mail, but you can cancel posts.
Find the article you wish to cancel (you can only cancel your own
articles, so don't try any funny stuff). Then press `C' or `S c'
(`gnus-summary-cancel-article'). Your article will be
canceled--machines all over the world will be deleting your article.
Be aware, however, that not all sites honor cancels, so your article
may live on here and there, while most sites will delete the article in
question.
If you discover that you have made some mistakes and want to do some
corrections, you can post a "superseding" article that will replace
your original article.
Go to the original article and press `S s'
(`gnus-summary-supersede-article'). You will be put in a buffer where
you can edit the article all you want before sending it off the usual
The same goes for superseding as for canceling, only more so: Some
sites do not honor superseding. On those sites, it will appear that you
have posted almost the same article twice.
If you have just posted the article, and change your mind right away,
there is a trick you can use to cancel/supersede the article without
waiting for the article to appear on your site first. You simply return
to the post buffer (which is called `*post-buf*'). There you will find
the article you just posted, with all the headers intact. Change the
`Message-ID' header to a `Cancel' or `Supersedes' header by
substituting one of those words for `Message-ID'. Then just press `C-c
C-c' to send the article as you would do normally. The previous
article will be canceled/superseded.
Just remember, kids: There is no 'c' in 'supersede'.

Marking Articles
================
There are several marks you can set on an article.
You have marks that decide the "readedness" (whoo, neato-keano
neologism ohoy!) of the article. Alphabetic marks generally mean
"read", while non-alphabetic characters generally mean "unread".
In addition, you also have marks that do not affect readedness.
* Menu:
* Unread Articles:: Marks for unread articles.
* Read Articles:: Marks for read articles.
* Other Marks:: Marks that do not affect readedness.
There's a plethora of commands for manipulating these marks:
* Menu:
* Setting Marks:: How to set and remove marks.
* Setting Process Marks:: How to mark articles for later processing.
File: gnus, Node: Unread Articles, Next: Read Articles, Up: Marking Articles
Unread Articles
---------------
The following marks mark articles as unread, in one form or other.
"Ticked articles" are articles that will remain visible always. If
you see an article that you find interesting, or you want to put
off reading it, or replying to it, until sometime later, you'd
typically tick it. However, articles can be expired, so if you
want to keep an article forever, you'll have to save it. Ticked
articles have a `!' (`gnus-ticked-mark') in the first column.
A "dormant" article is marked with a `?' (`gnus-dormant-mark'),
and will only appear in the summary buffer if there are followups
to it.
`SPACE'
An "unread" article is marked with a `SPACE' (`gnus-unread-mark').
These are articles that haven't been read at all yet.
File: gnus, Node: Read Articles, Next: Other Marks, Prev: Unread Articles, Up: Marking Articles
Read Articles
-------------
All the following marks mark articles as read.
Articles that are marked as read. They have a `r'
(`gnus-del-mark') in the first column. These are articles that the
user has marked as read more or less manually.
Articles that are actually read are marked with `R'
(`gnus-read-mark').
Articles that were marked as read in previous sessions are now
"old" and marked with `O' (`gnus-ancient-mark').
Marked as killed (`gnus-killed-mark').
Marked as killed by kill files (`gnus-kill-file-mark').
Marked as read by having a too low score (`gnus-low-score-mark').
Marked as read by a catchup (`gnus-catchup-mark').
Canceled article (`gnus-canceled-mark')
SOUPed article (`gnus-souped-mark').
Sparsely reffed article (`gnus-sparse-mark').
All these marks just mean that the article is marked as read, really.
They are interpreted differently by the adaptive scoring scheme,
however.
One more special mark, though:
You can also mark articles as "expirable" (or have them marked as
such automatically). That doesn't make much sense in normal
groups, because a user does not control the expiring of news
articles, but in mail groups, for instance, articles that are
marked as "expirable" can be deleted by Gnus at any time.
Expirable articles are marked with `E' (`gnus-expirable-mark').
File: gnus, Node: Other Marks, Next: Setting Marks, Prev: Read Articles, Up: Marking Articles
Other Marks
-----------
There are some marks that have nothing to do with whether the
article is read or not.
* You can set a bookmark in the current article. Say you are
reading a long thesis on cats' urinary tracts, and have to go home
for dinner before you've finished reading the thesis. You can
then set a bookmark in the article, and Gnus will jump to this
bookmark the next time it encounters the article.
* All articles that you have replied to or made a followup to (i.e.,
have answered) will be marked with an `A' in the second column
(`gnus-replied-mark').
* Articles that are stored in the article cache will be marked with
an `*' in the second column (`gnus-cached-mark').
* Articles that are "saved" (in some manner or other; not necessarily
religiously) are marked with an `S' in the second column
(`gnus-saved-mark'.
* It the `%e' spec is used, the presence of threads or not will be
marked with `gnus-not-empty-thread-mark' and
`gnus-empty-thread-mark' in the third column, respectively.
* Finally we have the "process mark" (`gnus-process-mark'. A
variety of commands react to the presence of the process mark. For
instance, `X u' (`gnus-uu-decode-uu') will uudecode and view all
articles that have been marked with the process mark. Articles
marked with the process mark have a `#' in the second column.
You might have noticed that most of these "non-readedness" marks
appear in the second column by default. So if you have a cached, saved,
replied article that you have process-marked, what will that look like?
Nothing much. The precedence rules go as follows: process -> cache
-> replied -> saved. So if the article is in the cache and is replied,
you'll only see the cache mark and not the replied mark.

Setting Marks
-------------
All the marking commands understand the numeric prefix.
`M t'
Tick the current article (`gnus-summary-tick-article-forward').
`M ?'
Mark the current article as dormant
(`gnus-summary-mark-as-dormant').
`M d'
Mark the current article as read
(`gnus-summary-mark-as-read-forward').
`M k'
Mark all articles that have the same subject as the current one as
read, and then select the next unread article
(`gnus-summary-kill-same-subject-and-select').
`M K'
`C-k'
Mark all articles that have the same subject as the current one as
read (`gnus-summary-kill-same-subject').
`M C'
Mark all unread articles in the group as read
(`gnus-summary-catchup').
`M C-c'
Mark all articles in the group as read--even the ticked and dormant
articles (`gnus-summary-catchup-all').
`M H'
Catchup the current group to point
(`gnus-summary-catchup-to-here').
`C-w'
Mark all articles between point and mark as read
(`gnus-summary-mark-region-as-read').
`M V k'
Kill all articles with scores below the default score (or below the
numeric prefix) (`gnus-summary-kill-below').
`M c'
`M-u'
Clear all readedness-marks from the current article
(`gnus-summary-clear-mark-forward').
`M e'
Mark the current article as expirable
(`gnus-summary-mark-as-expirable').
`M b'
Set a bookmark in the current article
(`gnus-summary-set-bookmark').
`M B'
Remove the bookmark from the current article
(`gnus-summary-remove-bookmark').
`M V c'
Clear all marks from articles with scores over the default score
(or over the numeric prefix) (`gnus-summary-clear-above').
`M V u'
Tick all articles with scores over the default score (or over the
numeric prefix) (`gnus-summary-tick-above').
`M V m'
Prompt for a mark, and mark all articles with scores over the
default score (or over the numeric prefix) with this mark
(`gnus-summary-clear-above').
The `gnus-summary-goto-unread' variable controls what action should
be taken after setting a mark. If non-`nil', point will move to the
next/previous unread article. If `nil', point will just move one line
up or down. As a special case, if this variable is `never', all the
marking commands as well as other commands (like `SPACE') will move to
the next article, whether it is unread or not. The default is `t'.

Limiting
========
It can be convenient to limit the summary buffer to just show some
subset of the articles currently in the group. The effect most limit
commands have is to remove a few (or many) articles from the summary
buffer.
`/ /'
`/ s'
Limit the summary buffer to articles that match some subject
(`gnus-summary-limit-to-subject').
`/ a'
Limit the summary buffer to articles that match some author
(`gnus-summary-limit-to-author').
`/ u'
Limit the summary buffer to articles that are not marked as read
(`gnus-summary-limit-to-unread'). If given a prefix, limit the
buffer to articles that are strictly unread. This means that
ticked and dormant articles will also be excluded.
`/ m'
Ask for a mark and then limit to all articles that have not been
marked with that mark (`gnus-summary-limit-to-marks').
`/ n'
Limit the summary buffer to the current article
(`gnus-summary-limit-to-articles'). Uses the process/prefix
convention (*note Process/Prefix::.).
`/ w'
Pop the previous limit off the stack and restore it
(`gnus-summary-pop-limit'). If given a prefix, pop all limits off
the stack.
`/ v'
Limit the summary buffer to articles that have a score at or above
some score (`gnus-summary-limit-to-score').
`/ E'
`M S'
Display all expunged articles
(`gnus-summary-limit-include-expunged').
`/ D'
Display all dormant articles
(`gnus-summary-limit-include-dormant').
`/ d'
Hide all dormant articles (`gnus-summary-limit-exclude-dormant').
`/ c'
Hide all dormant articles that have no children
(`gnus-summary-limit-exclude-childless-dormant').
`/ C'
Mark all excluded unread articles as read
(`gnus-summary-limit-mark-excluded-as-read'). If given a prefix,
also mark excluded ticked and dormant articles as read.
