Selecting a Group
=================

`SPACE'
     Select the current group, switch to the summary buffer and display
     the first unread article (`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, Gnus will fetch N number of articles.  If N is positive,
     fetch the N newest articles, if N is negative, fetch the ABS(N)
     oldest articles.

`RET'
     Select the current group and switch to the summary buffer
     (`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.

`M-RET'
     This does the same as the command above, but tries to do it with
     the minimum amount off fuzz (`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.

`M-SPACE'
     This is yet one more command that does the same as the one above,
     but this one does it without expunging and hiding dormants
     (`gnus-group-visible-select-group').

`c'
     Mark all unticked articles in this group as read
     (`gnus-group-catchup-current').  `gnus-group-catchup-group-hook'
     is when catching up a group from the group buffer.

`C'
     Mark all articles in this group, even the ticked ones, as read
     (`gnus-group-catchup-current-all').

   The `gnus-large-newsgroup' variable says what Gnus should consider
to be a big group.  This is 200 by default.  If the group has more
unread 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-auto-select-first' control whether any articles are selected
automatically when entering a group.

`nil'
     Don't select any articles when entering the group.  Just display
     the full summary buffer.

`t'
     Select the first unread article when entering the group.

`best'
     Select the most high-scored article in the group when entering the
     group.

   If you want to prevent automatic selection in some group (say, in a
binary group with Huge articles) you can set this variable to `nil' in
`gnus-select-group-hook', which is called when a group is selected.
