gnus-Subject-refer-parent-article). With a prefix argument, go
back to the child.
gnus-Subject-refer-article). With an empty Message-ID, go
back to the origin.
The command ^ (gnus-Subject-refer-parent-article) refers
to parent article of the current article. The child article is remembered in
internal history, and it is possible to return to the child by giving a
prefix argument to the command.
The commands ^ and M-r
(gnus-Subject-refer-parent-article and
gnus-Subject-refer-article) share the same internal history. You
can thus go back to a child using the command M-r with an empty
Message-ID.
Type g (gnus-Subject-show-article) to go back to the
origin from the visited articles directly.
See section Article Commands, to refer to articles by using Message-IDs included in the messages.
