1307 This buffer contains the results of the \"notmuch show\" command

1310 By default, various components of email messages, (citations,
1311 signatures, already-read messages), are hidden. You can make
1312 these parts visible by clicking with the mouse button or by
1313 pressing RET after positioning the cursor on a hidden part, (for
1314 which \\[notmuch-show-next-button] and \\[notmuch-show-previous-button] are helpful).
1316 Reading the thread sequentially is well-supported by pressing
1317 \\[notmuch-show-advance-and-archive]. This will scroll the current message (if necessary), advance
1318 to the next message, or advance to the next thread (if already on
1319 the last message of a thread).
1321 Other commands are available to read or manipulate the thread
1322 more selectively, (such as '\\[notmuch-show-next-message]' and '\\[notmuch-show-previous-message]' to advance to messages
1323 without removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread
1324 without scrolling through with \\[notmuch-show-advance-and-archive]).
1326 You can add or remove arbitrary tags from the current message with
