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