1359 By default, various components of email messages, (citations,
1360 signatures, already-read messages), are hidden. You can make

1362 pressing RET after positioning the cursor on a hidden part, (for

1365 Reading the thread sequentially is well-supported by pressing
1366 \\[notmuch-show-advance-and-archive]. This will scroll the current message (if necessary), advance
1367 to the next message, or advance to the next thread (if already on
1368 the last message of a thread).
1370 Other commands are available to read or manipulate the thread
1371 more selectively, (such as '\\[notmuch-show-next-message]' and '\\[notmuch-show-previous-message]' to advance to messages
1372 without removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread
1373 without scrolling through with \\[notmuch-show-advance-and-archive]).
1375 You can add or remove arbitrary tags from the current message with
