1260 This buffer contains the results of the \"notmuch show\" command
1261 for displaying a single thread of email from your email archives.
1263 By default, various components of email messages, (citations,
1264 signatures, already-read messages), are hidden. You can make
1265 these parts visible by clicking with the mouse button or by
1266 pressing RET after positioning the cursor on a hidden part, (for
1267 which \\[notmuch-show-next-button] and \\[notmuch-show-previous-button] are helpful).
1269 Reading the thread sequentially is well-supported by pressing
1270 \\[notmuch-show-advance-and-archive]. This will scroll the current message (if necessary), advance
1271 to the next message, or advance to the next thread (if already on
1272 the last message of a thread).
1274 Other commands are available to read or manipulate the thread
1275 more selectively, (such as '\\[notmuch-show-next-message]' and '\\[notmuch-show-previous-message]' to advance to messages
1276 without removing any tags, and '\\[notmuch-show-archive-thread]' to archive an entire thread
1277 without scrolling through with \\[notmuch-show-advance-and-archive]).
1279 You can add or remove arbitrary tags from the current message with
1280 '\\[notmuch-show-add-tag]' or '\\[notmuch-show-remove-tag]'.
