904 advance to the next message, or advance to the next thread (if
905 already on the last message of a thread). As each message is
906 scrolled away its \"unread\" tag will be removed, and as each
907 thread is scrolled away the \"inbox\" tag will be removed from
908 each message in the thread.

911 selectively, (such as '\\[notmuch-show-next-message]' and '\\[notmuch-show-previous-message]' to advance to messages without
912 removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread without
913 scrolling through with \\[notmuch-show-advance-marking-read-and-archiving]).
