All the straight movement commands understand the numeric prefix and behave pretty much as you'd expect.
None of these commands select articles.
gnus-summary-next-unread-subject).gnus-summary-prev-unread-subject).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-nextt 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 with unread articles. 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 see Group Levels.gnus-auto-select-samenil, 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 (see 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-currentnil, 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-summarynil, 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.
gnus-summary-stop-at-end-of-messagenil, don't go to the next article when
hitting SPC, and you're at the end of the
article.
