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 g'
Ask for an article number and then go to the summary line of that
article without displaying the 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 issue one of the movement commands (like `n') and there are
no more unread articles after the current one, 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. ("Same" here might
mean "roughly equal". See `gnus-summary-gather-subject-limit' for
details (Note:Customizing Threading).) If there are no more
articles with the same subject, go to the first unread article.
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.
This variable can also be a number. In that case, center the
window at the given number of lines from the top.
