1323 This buffer contains the results of the \"notmuch show\" command

1326 By default, various components of email messages, (citations,
1327 signatures, already-read messages), are hidden. You can make
1328 these parts visible by clicking with the mouse button or by
1329 pressing RET after positioning the cursor on a hidden part, (for
1330 which \\[notmuch-show-next-button] and \\[notmuch-show-previous-button] are helpful).
1332 Reading the thread sequentially is well-supported by pressing
1333 \\[notmuch-show-advance-and-archive]. This will scroll the current message (if necessary), advance
1334 to the next message, or advance to the next thread (if already on
1335 the last message of a thread).
1337 Other commands are available to read or manipulate the thread
1338 more selectively, (such as '\\[notmuch-show-next-message]' and '\\[notmuch-show-previous-message]' to advance to messages
1339 without removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread
1340 without scrolling through with \\[notmuch-show-advance-and-archive]).
1342 You can add or remove arbitrary tags from the current message with
