The Newsgroup buffer normally lists the newsgroups which you subscribe to and which contain unread articles. But not always--some of the things you can do display additional newsgroups. The commands available in this buffer are mostly concerned with subscribing and unsubscribing.
Most of the newsgroup commands operate on the group described by the current line. To use them, you need to move the cursor to the group you want to act on. You can use ordinary Emacs motion commands, or these special commands:
gnus-group-next-unread-group).
gnus-group-prev-unread-group).
gnus-group-next-group).
gnus-group-prev-group).
gnus-group-jump-to-group).
beginning-of-buffer).
end-of-buffer).
gnus-group-restrict-groups).
The command j (gnus-group-jump-to-group) reads a
newsgroup name interactively, and moves point to it. If there is no
such newsgroup in the buffer, a line for the newsgroup is inserted at
the beginning of the buffer.
The command r (gnus-group-restrict-groups) restricts
visibility in the Newsgroup buffer to the region specified by point and
mark. It is not quite the same as C-x n; it includes all of the
line that the region starts in, and all of the line that the region ends
in. Type C-x w (widen) to widen visibility to the whole
buffer.
To start reading the articles in a newsgroup, move to that newsgroup
in the Newsgroup buffer and type SPC
(gnus-group-read-group) or =
(gnus-group-select-group).
gnus-group-read-group).
gnus-group-select-group).
Normally, when you select a newsgroup, GNUS prepares to read only the
unread articles (including saved articles). If the newsgroup has no
unread articles and you select it anyway, GNUS prepares to read all the
articles. You can force GNUS to include all the articles by giving a
prefix argument to the commands SPC and =
(gnus-group-read-group and gnus-group-select-group).
If the number of articles being selected is larger than the variable
gnus-large-newsgroup, GNUS prompts for the number of articles to
prepare. If your answer n is positive, GNUS prepares the last
n articles. If n is negative, GNUS prepares the first
-n articles. If you answer with the empty string, GNUS
prepares all articles.
This section explains how to subscribe and unsubscribe, as well as other related activities. Most of the commands operate on the newsgroup listed on the current line.
gnus-group-catchup).
gnus-group-catchup-all).
gnus-group-list-groups).
gnus-group-list-all-groups).
gnus-group-unsubscribe-current-group).
gnus-group-unsubscribe-group).
gnus-group-kill-group).
gnus-group-kill-region).
gnus-group-yank-group). It is
inserted just before the current line. Successive uses of C-y
yank earlier kills, in last-in first-out order.
gnus-group-transpose-groups).gnus-group-check-bogus-groups).
gnus-group-get-new-news).
The commands c and C (gnus-group-catchup and
gnus-group-catchup-all) mark all or most of the articles in a
newsgroup as read. They are useful if you have been away from news
reading for a while, and you don't want to slog through the backlog of
old postings. These commands do not take account of the cross-reference
information in the `Xref:' field, while the c command in
Summary Mode does.
Only subscribed newsgroups containing unread and saved articles are usually
displayed in the Newsgroup buffer. Type L
(gnus-group-list-all-groups) to show all newsgroups which are
currently active. Use l (gnus-group-list-groups) to go
back to the usual contents--only groups which have news for you to
read.
The command U (gnus-group-unsubscribe-group) reads a
newsgroup name interactively, and toggles its subscription flag. This
is the usual way to subscribe to new groups. (You can also type L
and then use u on the groups you want to read.) You can also
arrange to subscribe automatically to some or all newly created
newsgroups using the options line in your startup file, `~/.newsrc'.
See section The Startup File, for more information.
The command C-k (gnus-group-kill-group) kills a newsgroup
from both the Newsgroup buffer and the raw startup file. If you change
your mind, type C-y (gnus-group-yank-group); this yanks the
last newsgroup killed with the C-k command.
The command C-c C-l (gnus-list-killed-groups) pops up a buffer listing
the newsgroups you have killed. You can yank any of these newsgroups by
moving point to the entry for the newsgroup you want, and then typing
y or C-y (gnus-browse-killed-yank). So a convenient
way to change the order of newsgroups is to kill some of them, then go
to the list of killed groups and yank them in the order you want.
You are not limited to yanking only the groups that you killed in the current GNUS session. All the groups you have ever killed are remembered in the quick startup file, and you can restore them any time unless you lose the file.
A bogus newsgroup is one not in the list of active newsgroups in
the active file. Type b (gnus-group-check-bogus-groups) to
delete all the bogus newsgroups that you subscribe to. Bogus newsgroups
that you have unsubscribed or killed are deleted also.
The g command rereads the active file to get updated lists of articles available to be read.
gnus-group-suspend).
gnus-group-exit).
gnus-group-quit).
Suspending GNUS with z (gnus-group-suspend) kills all
GNUS buffers except for the Newsgroup buffer. To resume again, switch
to the Newsgroup buffer and type g
(gnus-group-get-new-news) to get newly arrived articles. It is a
good idea to update the startup file (see section The Startup File) before
suspending GNUS.
If you want to forget what you read this GNUS session, exit GNUS by
the command Q (gnus-group-quit). Otherwise, exit by the
command q (gnus-group-exit) to update the startup
file.
The hook gnus-exit-gnus-hook is called when exiting GNUS, and
the hook gnus-suspend-gnus-hook is called when suspending GNUS.
Other miscellaneous Group mode commands are described here.
gnus-group-post-news). See section Posting Articles, for more information.
gnus-group-edit-local-kill). See section Kill File, for more information.
gnus-group-edit-global-kill).
See section Kill File, for more information.
