885 scrolled away its \"unread\" tag will be removed, and as each
886 thread is scrolled away the \"inbox\" tag will be removed from

891 removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread without
892 scrolling through with \\[notmuch-show-advance-marking-read-and-archiving]).
