Exiting from the summary buffer will normally update all info on the group and return you to the group buffer.
gnus-summary-prepare-exit-hookis called before doing much of the exiting, which calls
gnus-summary-exit-hookis called after finishing the exit process.
gnus-group-no-more-groups-hookis run when returning to group mode having no more (unread) groups.
gnus-summary-reselect-current-group). If given a prefix, select all articles, both read and unread.
gnus-summary-rescan-group). If given a prefix, select all articles, both read and unread.
gnus-summary-save-newsrc). If given a prefix, also save the .newsrc file(s). Using this command will make exit without updating (the Q command) worthless.
gnus-exit-group-hook is called when you exit the current group
with an “updating” exit. For instance Q
gnus-summary-exit-no-update) does not call this hook.
If you're in the habit of exiting groups, and then changing your mind
about it, you might set
If you do that, Gnus won't kill the summary buffer when you exit it.
(Quelle surprise!) Instead it will change the name of the buffer to
something like ‘*Dead Summary ... *’ and install a minor mode
gnus-dead-summary-mode. Now, if you switch back to this
buffer, you'll find that all keys are mapped to a function called
gnus-summary-wake-up-the-dead. So tapping any keys in a dead
summary buffer will result in a live, normal summary buffer.
There will never be more than one dead summary buffer at any one time.
The data on the current group will be updated (which articles you have
read, which articles you have replied to, etc.) when you exit the
summary buffer. If the
gnus-use-cross-reference variable is
t (which is the default), articles that are cross-referenced to
this group and are marked as read, will also be marked as read in the
other subscribed groups they were cross-posted to. If this variable is
t, the article will be marked as read in
both subscribed and unsubscribed groups (see Crosspost Handling).
