gnus-group-read-group). If there are no unread articles in the group, or if you give a non-numerical prefix to this command, Gnus will offer to fetch all the old articles in this group from the server. If you give a numerical prefix n, n determines the number of articles Gnus will fetch. If n is positive, Gnus fetches the n newest articles, if n is negative, Gnus fetches the
Thus, <SPC> enters the group normally, C-u <SPC> offers old articles, C-u 4 2 <SPC> fetches the 42 newest articles, and C-u - 4 2 <SPC> fetches the 42 oldest ones.
When you are in the group (in the Summary buffer), you can type
M-g to fetch new articles, or C-u M-g to also show the old
gnus-group-select-group). Takes the same arguments as
gnus-group-read-group—the only difference is that this command does not display the first unread article automatically upon group entry.
gnus-group-quick-select-group). No scoring/killing will be performed, there will be no highlights and no expunging. This might be useful if you're in a real hurry and have to enter some humongous group. If you give a 0 prefix to this command (i.e., 0 M-<RET>), Gnus won't even generate the summary buffer, which is useful if you want to toggle threading before generating the summary buffer (see Summary Generation Commands).
gnus-group-select-group-ephemerally). Even threading has been turned off. Everything you do in the group after selecting it in this manner will have no permanent effects.
gnus-large-newsgroup variable says what Gnus should
consider to be a big group. If it is
nil, no groups are
considered big. The default value is 200. If the group has more
(unread and/or ticked) articles than this, Gnus will query the user
before entering the group. The user can then specify how many
articles should be fetched from the server. If the user specifies a
negative number (-n), the n oldest articles will be
fetched. If it is positive, the n articles that have arrived
most recently will be fetched.
gnus-large-ephemeral-newsgroup is the same as
gnus-large-newsgroup, but is only used for ephemeral
In groups in some news servers, there might be a big gap between a few
very old articles that will never be expired and the recent ones. In
such a case, the server will return the data like
(1 . 30000000)
LIST ACTIVE group command, for example. Even if there
are actually only the articles 1–10 and 29999900–30000000, Gnus doesn't
know it at first and prepares for getting 30000000 articles. However,
it will consume hundreds megabytes of memories and might make Emacs get
stuck as the case may be. If you use such news servers, set the
gnus-newsgroup-maximum-articles to a positive number.
The value means that Gnus ignores articles other than this number of the
latest ones in every group. For instance, the value 10000 makes Gnus
get only the articles 29990001–30000000 (if the latest article number is
30000000 in a group). Note that setting this variable to a number might
prevent you from reading very old articles. The default value of the
means Gnus never ignores old articles.
gnus-auto-select-first is non-
nil, select an article
automatically when entering a group with the <SPC> command.
Which article this is controlled by the
gnus-auto-select-subject variable. Valid values for this
This variable can also be a function. In that case, that function will be called to place point on a subject line.
If you want to prevent automatic selection in some group (say, in a
binary group with Huge articles) you can set the
gnus-auto-select-first variable to
gnus-select-group-hook, which is called when a group is
