1 # Tips and Tricks for using notmuch with Emacs
3 One of the more popular notmuch message reading clients is
4 **notmuch.el**, an [emacs](http://www.gnu.org/software/emacs/) major
5 mode for interacting with notmuch. It is included in the notmuch
6 package (notmuch-emacs in Debian). This page goes over some usage
7 tips for using notmuch with Emacs.
13 Have a look at the [Howto](http://notmuchmail.org/howto/) for
14 prerequisites. Be sure you have done the general setup using the
17 To use the Notmuch emacs mode, first add the following line to your
22 or you can load the package via autoload:
24 (autoload 'notmuch "notmuch" "notmuch mail" t)
26 Then, either run "emacs -f notmuch", or execute the command `M-x
27 notmuch` from within a running emacs.
29 ## Navigating & reading mails
31 When first starting notmuch in emacs, you will be presented with the
32 notmuch "hello" page. If it exits with an error after writing
33 "Welcome to notmutch. You have" you need to do the basic notmuch setup
35 From here you can do searches, see lists of recent
36 searches, saved searches, message tags, help information, etc.
38 Executing a search will open a new buffer in `notmuch-search-mode`
39 displaying the search results. Each line in the search results
40 represents a message thread. Hitting the '?' key will show help for
43 In general, the 'q' will kill the current notmuch buffer and return
44 you to the previous buffer (sort of like a 'pop').
46 In search mode, navigating to a thread and hitting return will then
47 open a new buffer in `notmuch-show-mode`, which will show the actual
48 message contents of the thread.
52 In any notmuch mode, you can start a new message by hitting the 'm'
53 key. To reply to a message or thread, just hit the 'r' key.
55 When composing new messages, you will be entered in emacs's
56 `message-mode`, which is a powerful mode for composing and sending
57 messages. When in message mode, you can type `C-c ?` for help.
59 If you would like to use address autocompletion when composing
60 messages, see [address completion](#address_completion).
62 When you are ready to send a message, type `C-c C-c`. By default
63 message mode will use your sendmail command to send mail, so make sure
64 that works. One annoying standard configuration of message mode is
65 that it will hide the sent mail in your emacs frame stack, but it will
66 not close it. If you type several mails in an emacs session they will
67 accumulate and make switching between buffers more annoying. You can
68 avoid that behavior by adding `(setq message-kill-buffer-on-exit t)`
69 in your `.emacs` file (or doing `M-x
70 customize-variable<RET>message-kill-buffer-on-exit<RET>`) which will
71 really close the mail window after sending it.
75 Using the `M-x mml-attach-file` command, you can attach any file to be
76 sent with your mail. By default this command is bound to the menu item
77 *Attachments--Attach File* with the key binding `C-c C-a`. The
78 variable `mml-dnd-attach-options` (`M-x
79 customize-variable<RET>mml-dnd-attach-options<RET>`) can be set to
80 allow the prompting for various attachment options (such as
81 inline/attachment) if you want to do that.
83 For those who prefer a more graphical interface, you can also simply
84 drag and drop files from a file manager into a mail composition window
85 to have them attached. In Ubuntu this works without any modifications
86 if files are dragged from the file manager.
88 And for those who prefer working from command line, the following
89 script opens new emacs window with empty message and attaches files
90 mentioned as script arguments. (Note: The script expects that you have
91 `(server-start)` in your `.emacs` file.)
96 fullpath=$(readlink --canonicalize "$1")
97 attach_cmds="$attach_cmds (mml-attach-file \"$fullpath\")"
100 emacsclient -a '' -c -e "(progn (compose-mail) $attach_cmds)"
102 ## Issues with Emacs 24
104 If notmuch-show-mode behaves badly for you in emacs 24.x try adding one of
106 (setq gnus-inhibit-images nil)
116 # Advanced tips and tweaks
118 ## Use separate emacs lisp file for notmuch configuration
120 Instead of adding notmuch configuration code to `.emacs`, there
121 is an option to collect those to a separate file (which is only
122 loaded when `notmuch` is invoked). To do this, write, for example
123 a file called `~/.emacs.d/my-notmuch.el`:
125 ;;; my-notmuch.el -- my notmuch mail configuration
128 ;;; add here stuff required to be configured *before*
129 ;;; notmuch is loaded;
131 ;; uncomment and modify in case some elisp files are not found in load-path
132 ;; (add-to-list 'load-path "~/vc/ext/notmuch/emacs")
137 ;;; add here stuff required to be configured *after*
138 ;;; notmuch is loaded;
140 ;; uncomment & modify if you want to use external smtp server to send mail
141 ;; (setq smtpmail-smtp-server "smtp.server.tld"
142 ;; message-send-mail-function 'message-smtpmail-send-it)
143 ;; uncomment to debug smtp sending problems
144 ;; (setq smtpmail-debug-info t)
146 Then, add to `.emacs`:
148 (autoload 'notmuch "~/.emacs.d/my-notmuch" "notmuch mail" t)
150 ## Initial cursor position in notmuch 0.15 hello window
152 In notmuch version 0.15 emacs client the handling of cursor position in
153 notmuch hello window has been simplified to a version which suits best
156 Initially the cursor is positioned at the beginning of buffer.
158 Some users liked the "ancient" version where cursor was moved to the
159 first `Saved searches` button.
161 Add the following code to your notmuch emacs configuration file in
162 case you want this behaviour:
164 (add-hook 'notmuch-hello-refresh-hook
166 (if (and (eq (point) (point-min))
167 (search-forward "Saved searches:" nil t))
171 (if (eq (widget-type (widget-at)) 'editable-field)
172 (beginning-of-line)))))
174 ## Add a key binding to add/remove/toggle a tag
176 The `notmuch-{search,show}-{add,remove}-tag` functions are very useful
177 for making quick tag key bindings. For instance, here's an example
178 of how to make a key binding to add the "spam" tag and remove the
179 "inbox" tag in notmuch-show-mode:
181 In notmuch versions up to 0.11.x
183 (define-key notmuch-show-mode-map "S"
185 "mark message as spam"
187 (notmuch-show-add-tag "spam")
188 (notmuch-show-remove-tag "inbox")))
190 Starting from notmuch 0.12 the functions `notmuch-show-add-tag` and
191 `notmuch-show-remove-tag` have changed to be more versatile and lost
192 noninteractive use. When upgrading to 0.12 the above needs to be
195 (define-key notmuch-show-mode-map "S"
197 "mark message as spam"
199 (notmuch-show-tag-message "+spam" "-inbox")))
201 You can do the same for threads in `notmuch-search-mode` by just
202 replacing "show" with "search" in the called functions.
204 Starting from notmuch 0.12 use `notmuch-search-tag-thread` instead:
206 (define-key notmuch-search-mode-map "S"
208 "mark messages in thread as spam"
210 (notmuch-show-tag-thread "+spam" "-inbox")))
212 Starting from notmuch 0.13 use `notmuch-search-tag` -- it has a little
213 different usage syntax:
215 (define-key notmuch-search-mode-map "S"
217 "mark messages in thread as spam"
219 (notmuch-search-tag '("+spam" "-inbox"))))
221 The definition above makes use of a lambda function, but you could
222 also define a separate function first:
224 (defun notmuch-show-tag-spam ()
225 "mark message as spam"
227 (notmuch-show-add-tag "spam")
228 (notmuch-show-remove-tag "inbox")))
229 (define-key notmuch-show-mode-map "S" 'notmuch-show-tag-spam)
231 (See above for analogy how to apply this for notmuch 0.12 and later)
233 Here's a more complicated example of how to add a toggle "deleted"
236 (define-key notmuch-show-mode-map "d"
238 "toggle deleted tag for message"
240 (if (member "deleted" (notmuch-show-get-tags))
241 (notmuch-show-remove-tag "deleted")
242 (notmuch-show-add-tag "deleted"))))
244 And version for notmuch 0.12
246 (define-key notmuch-show-mode-map "d"
248 "toggle deleted tag for message"
250 (notmuch-show-tag-message
251 (if (member "deleted" (notmuch-show-get-tags))
252 "-deleted" "+deleted"))))
254 ## Adding many tagging keybindings
256 If you want to have have many tagging keybindings, you can save the typing
257 the few lines of boilerplate for every binding (for versions before 0.12,
258 you will need to change notmuch-show-apply-tag-macro).
260 (eval-after-load 'notmuch-show
261 '(define-key notmuch-show-mode-map "`" 'notmuch-show-apply-tag-macro))
263 (setq notmuch-show-tag-macro-alist
265 '("m" "+notmuch::patch" "+notmuch::moreinfo" "-notmuch::needs-review")
266 '("n" "+notmuch::patch" "+notmuch::needs-review" "-notmuch::pushed")
267 '("o" "+notmuch::patch" "+notmuch::obsolete"
268 "-notmuch::needs-review" "-notmuch::moreinfo")
269 '("p" "-notmuch::pushed" "-notmuch::needs-review"
270 "-notmuch::moreinfo" "+pending")
271 '("P" "-pending" "-notmuch::needs-review" "-notmuch::moreinfo" "+notmuch::pushed")
272 '("r" "-notmuch::patch" "+notmuch::review")
273 '("s" "+notmuch::patch" "-notmuch::obsolete" "-notmuch::needs-review" "-notmuch::moreinfo" "+notmuch::stale")
274 '("t" "+notmuch::patch" "-notmuch::needs-review" "+notmuch::trivial")
275 '("w" "+notmuch::patch" "+notmuch::wip" "-notmuch::needs-review")))
277 (defun notmuch-show-apply-tag-macro (key)
279 (let ((macro (assoc key notmuch-show-tag-macro-alist)))
280 (apply 'notmuch-show-tag-message (cdr macro))))
282 ## Restore reply-to-all key binding to 'r'
284 Starting from notmuch 0.12 the 'r' key is bound to reply-to-sender instead of
285 reply-to-all. Here's how to swap the reply to sender/all bindings in show mode:
287 (define-key notmuch-show-mode-map "r" 'notmuch-show-reply)
288 (define-key notmuch-show-mode-map "R" 'notmuch-show-reply-sender)
292 (define-key notmuch-search-mode-map "r" 'notmuch-search-reply-to-thread)
293 (define-key notmuch-search-mode-map "R" 'notmuch-search-reply-to-thread-sender)
296 ## How to do FCC/BCC...
298 The Emacs interface to notmuch will automatically add an `Fcc`
299 header to your outgoing mail so that any messages you send will also
300 be saved in your mail store. You can control where this copy of the
301 message is saved by setting the variable `notmuch-fcc-dirs` which defines the
302 subdirectory relative to the `database.path` setting from your
303 notmuch configuration in which to save the mail. Enter a directory
304 (without the maildir `/cur` ending which will be appended
305 automatically). Additional information can be found as usual using:
307 M-x describe-variable notmuch-fcc-dirs
309 An additional variable that can affect FCC settings in some cases is
310 `message-directory`. Emacs message-mode uses this variable for
313 To customize both variables at the same time, use the fancy command:
315 M-x customize-apropos<RET>\(notmuch-fcc-dirs\)\|\(message-directory\)
317 This mechanism also allows you to select different folders to be
318 used for the outgoing mail depending on your selected `From`
319 address. Please see the documentation for the variable
320 `notmuch-fcc-dirs` in the customization window for how to arrange
323 ## How to customize `notmuch-saved-searches`
325 When starting notmuch, a list of saved searches and message counts is
326 displayed, replacing the older `notmuch-folders` command. The set of
327 saved searches displayed can be modified directly from the notmuch
328 interface (using the `[save]` button next to a previous search) or by
329 customising the variable `notmuch-saved-searches`.
331 An example setting might be:
333 (setq notmuch-saved-searches '(("inbox" . "tag:inbox")
334 ("unread" . "tag:inbox AND tag:unread")
335 ("notmuch" . "tag:inbox AND to:notmuchmail.org")))
337 Of course, you can have any number of saved searches, each configured
338 with any supported search terms (see "notmuch help search-terms").
340 Some users find it useful to add `and not tag:delete` to those
341 searches, as they use the `delete` tag to mark messages as
342 deleted. This causes messages that are marked as deleted to be removed
343 from the commonly used views of messages. Use whatever seems most
346 ## Viewing HTML messages with an external viewer
348 The emacs client can display an HTML message inline using either the
349 `html2text` library or some text browser, like w3m or lynx. This is
350 controlled by the `mm-text-html-renderer` variable.
352 The first option is theorically better, because it can generate
353 strings formatted for emacs and do whatever you want, e.g., substitute
354 text inside <b> tags for bold text in the buffer. The library, however
355 is still in a very early development phase and cannot yet process
356 properly many elements, like tables and <style> directives, and even
357 the generated text is often poorly formatted.
359 Among the available browsers, w3m seems to do a better job converting
360 the html, and if you have the w3m emacs package, you can use it,
361 instead of the w3m-standalone, and thus preserve the text formatting.
363 But if the rendering fails for one reason or another, or if you really
364 need to see the graphical presentation of the HTML message, it can be
365 useful to display the message in an external viewer, such as a web
366 browser. Here's a little script that Keith Packard wrote, which he
372 cat "$@" > "$dir"/msg
373 if munpack -C "$dir" -t < "$dir"/msg 2>&1 | grep 'Did not find'; then
374 sed -n '/[Hh][Tt][Mm][Ll]/,$p' "$dir"/msg > $dir/part1.html
377 for i in "$dir"/part*; do
378 if grep -q -i -e '<html>' -e 'text/html' "$i"; then
385 Save that script somewhere in your `${PATH}`, make it executable,
386 and change the invocation of `iceweasel` to any other HTML viewer if
387 necessary. Then within the emacs client, press '|' to pipe the
388 current message, then type "view-html".
390 Keith mentions the following caveat, "Note that if iceweasel isn't
391 already running, it seems to shut down when the script exits. I
394 ## msmtp, message mode and multiple accounts
396 As an alternative to running a mail server such as sendmail or postfix
397 just to send email, it is possible to use
398 [msmtp](http://msmtp.sourceforge.net/). This small application will
399 look like `/usr/bin/sendmail` to a MUA such as emacs message mode, but
400 will just forward the email to an external SMTP server. It's fairly
401 easy to set up and it supports several accounts for using different
402 SMTP servers. The msmtp pages have several examples.
404 A typical scenario is that you want to use the company SMTP server
405 for email coming from your company email address, and your personal
406 server for personal email. If msmtp is passed the envelope address
407 on the command line (the -f/--from option) it will automatically
408 pick the matching account. The only trick here seems to be getting
409 emacs to actually pass the envelope from. There are a number of
410 overlapping configuration variables that control this, and it's a
411 little confusion, but setting these three works for me:
413 - `mail-specify-envelope-from`: `t`
415 - `message-sendmail-envelope-from`: `header`
417 - `mail-envelope-from`: `header`
419 With that in place, you need a `.msmtprc` with the accounts configured
420 for the domains you want to send out using specific SMTP servers and
421 the rest will go to the default account.
423 If you have a hard time getting the above to work for you, as I did,
424 it's also possible to add a message-send-mail-hook in your .emacs to
425 send the from header explicitly as an argument to msmtp as described
426 [here](http://www.emacswiki.org/cgi-bin/wiki/GnusMSMTP#toc2) on the
430 ## <span id="address_completion">Address completion when composing</span>
432 There are currently three solutions to this:
436 [bbdb](http://bbdb.sourceforge.net) is a contact database for emacs
437 that works quite nicely together with message mode, including
438 address autocompletion.
440 ### notmuch database as an address book
442 You can also use the notmuch database as a mail address book itself.
443 To do this you need a command line tool that outputs likely address
444 candidates based on a search string. There are currently three
447 * The python tool `notmuch_address.py` (`git clone
448 http://commonmeasure.org/~jkr/git/notmuch_addresses.git`) (slower, but
449 no compilation required so good for testing the setup)
452 [addrlookup](http://github.com/spaetz/vala-notmuch) (faster, but
453 needs compiling). The addrlookup binary needs to be compiled.
455 `http://github.com/spaetz/vala-notmuch/raw/static-sources/src/addrlookup.c`
458 cc -o addrlookup addrlookup.c `pkg-config --cflags --libs gobject-2.0` -lnotmuch
460 * Shell/fgrep/perl combination [nottoomuch-addresses.sh](https://github.com/domo141/nottoomuch/blob/master/nottoomuch-addresses.rst).
461 This tools maintains it's own address "database" gathered from email
462 files notmuch knows and search from that "database" is done by `fgrep(1)`.
464 You can perform tab-completion using any of these programs.
465 Just add the following to your .emacs:
467 (require 'notmuch-address)
468 (setq notmuch-address-command "/path/to/address_fetching_program")
469 (notmuch-address-message-insinuate)
473 [GooBook](http://code.google.com/p/goobook/) is a command-line tool for
474 accessing Google Contacts. Install and set it up according to its documentation.
476 To use GooBook with notmuch, use this wrapper script and set it up like the
480 goobook query "$*" | sed 's/\(.*\)\t\(.*\)\t.*/\2 \<\1\>/' | sed '/^$/d'
482 You can add the sender of a message to Google Contacts by piping the message
483 (`notmuch-show-pipe-message`) to `goobook add`.
485 ## How to sign/encrypt messages with gpg
487 Messages can by signed using gpg by invoking
488 `M-x mml-secure-sign-pgpmime` (or `M-x mml-secure-encrypt-pgpmime`).
489 These functions are available via the standard `message-mode` keybindings
490 `C-c C-m s p` and `C-c C-m c p`. To sign outgoing mail by default, use the
491 `message-setup-hook` in your `.emacs` file:
493 ;; Sign messages by default.
494 (add-hook 'message-setup-hook 'mml-secure-sign-pgpmime)
496 This inserts the required `<#part sign=pgpmime>` into the beginning
497 of the mail text body and will be converted into a pgp signature
498 when sending (so one can just manually delete that line if signing
501 Alternatively, you may prefer to use `mml-secure-message-sign-pgpmime` instead
502 of `mml-secure-sign-pgpmime` to sign the whole message instead of just one
505 ### Troubleshooting message-mode gpg support
507 - If you have trouble with expired subkeys, you may have encountered
508 emacs bug #7931. This is fixed in git commit 301ea744c on
509 2011-02-02. Note that if you have the Debian package easypg
510 installed, it will shadow the fixed version of easypg included with
513 ## Multiple identities using gnus-alias
515 [gnus-alias](http://www.emacswiki.org/emacs/GnusAlias) allows you to
516 define multiple identities when using `message-mode`. You can specify
517 the from address, organization, extra headers (including *Bcc*), extra
518 body text, and signature for each identity. Identities are chosen
519 based on a set of rules. When you are in message mode, you can switch
520 identities using gnus-alias.
524 - put `gnus-alias.el` on your load Emacs-Lisp load path (add new directory
525 to load path by writing `(add-to-list 'load-path "/some/load/path")` into
528 - Add the following to your `.emacs`
530 (autoload 'gnus-alias-determine-identity "gnus-alias" "" t)
531 (add-hook 'message-setup-hook 'gnus-alias-determine-identity)
533 Looking into `gnus-alias.el` gives a bit more information...
535 ### Example Configuration
537 Here is an example configuration.
539 ;; Define two identities, "home" and "work"
540 (setq gnus-alias-identity-alist
542 nil ;; Does not refer to any other identity
543 "John Doe <jdoe@example.net>" ;; Sender address
544 nil ;; No organization header
545 nil ;; No extra headers
546 nil ;; No extra body text
550 "John Doe <john.doe@example.com>"
552 (("Bcc" . "john.doe@example.com"))
554 "~/.signature.work")))
555 ;; Use "home" identity by default
556 (setq gnus-alias-default-identity "home")
557 ;; Define rules to match work identity
558 (setq gnus-alias-identity-rules
559 '(("work" ("any" "john.doe@\\(example\\.com\\|help\\.example.com\\)" both) "work"))
560 ;; Determine identity when message-mode loads
561 (add-hook 'message-setup-hook 'gnus-alias-determine-identity)
563 When `gnus-alias` has been loaded (using autoload, require, *M-x load-library*
564 or *M-x load-file* (load-file takes file path -- therefore it can be used
565 without any `.emacs` changes)) the following commands can be used to get(/set)
566 more information (some of these have "extensive documentation"):
568 M-x describe-variable RET gnus-alias-identity-alist
569 M-x describe-variable RET gnus-alias-identity-rules
570 M-x describe-variable RET gnus-alias-default-identity
572 M-x customize-group RET gnus-alias RET
574 M-x gnus-alias-customize RET
576 The last two do the same thing.
578 See also the **Usage:** section in `gnus-alias.el`.
580 ## Resending (or bouncing) messages
582 Add the following to your `.emacs` to be able to resend the current message in
585 (define-key notmuch-show-mode-map "b"
586 (lambda (&optional address)
587 "Bounce the current message."
588 (interactive "sBounce To: ")
589 (notmuch-show-view-raw-message)
590 (message-resend address)))
592 ## `notmuch-hello` refresh status message
594 Add the following to your `.emacs` to get a status message about the change in
595 the number of messages in the mail store when refreshing the `notmuch-hello`
598 (defvar notmuch-hello-refresh-count 0)
600 (defun notmuch-hello-refresh-status-message ()
604 (car (process-lines notmuch-command "count"))))
605 (diff-count (- new-count notmuch-hello-refresh-count)))
607 ((= notmuch-hello-refresh-count 0)
608 (message "You have %s messages."
609 (notmuch-hello-nice-number new-count)))
611 (message "You have %s more messages since last refresh."
612 (notmuch-hello-nice-number diff-count)))
614 (message "You have %s fewer messages since last refresh."
615 (notmuch-hello-nice-number (- diff-count)))))
616 (setq notmuch-hello-refresh-count new-count))))
618 (add-hook 'notmuch-hello-refresh-hook 'notmuch-hello-refresh-status-message)
620 ## Replacing tabs with spaces in subject and header
622 Mailman mailing list software rewrites and rewraps long message subjects in
623 a way that causes TABs to appear in the middle of the subject and header
624 lines. Add this to your `.emacs` to replace tabs with spaces in subject
627 (defun notmuch-show-subject-tabs-to-spaces ()
628 "Replace tabs with spaces in subject line."
629 (goto-char (point-min))
630 (when (re-search-forward "^Subject:" nil t)
631 (while (re-search-forward "\t" (line-end-position) t)
632 (replace-match " " nil nil))))
634 (add-hook 'notmuch-show-markup-headers-hook 'notmuch-show-subject-tabs-to-spaces)
636 And in header lines (this will only work with the yet to be released
637 notmuch version 0.15):
639 (defun notmuch-show-header-tabs-to-spaces ()
640 "Replace tabs with spaces in header line."
641 (setq header-line-format
642 (notmuch-show-strip-re
643 (replace-regexp-in-string "\t" " " (notmuch-show-get-subject)))))
645 (add-hook 'notmuch-show-hook 'notmuch-show-header-tabs-to-spaces)
647 ## Hiding unread messages in notmuch-show
649 I like to have an inbox saved search, but only show unread messages when they
650 view a thread. This takes two steps:
653 [this patch from Mark Walters](http://notmuchmail.org/pipermail/notmuch/2012/010817.html)
654 to add the `notmuch-show-filter-thread` function.
655 1. Add the following hook to your emacs configuration:
657 (defun expand-only-unread-hook () (interactive)
659 (open (notmuch-show-get-message-ids-for-open-messages)))
660 (notmuch-show-mapc (lambda ()
661 (when (member "unread" (notmuch-show-get-tags))
664 (let ((notmuch-show-hook (remove 'expand-only-unread-hook notmuch-show-hook)))
665 (notmuch-show-filter-thread "tag:unread")))))
667 (add-hook 'notmuch-show-hook 'expand-only-unread-hook)
669 ## Changing the color of a saved search based on some other search
671 I like to have a saved search for my inbox, but have it change color when there
672 are thread with unread messages in the inbox. I accomplish this with the
673 following code in my emacs config:
675 (defun color-inbox-if-unread () (interactive)
677 (goto-char (point-min))
678 (let ((cnt (car (process-lines "notmuch" "count" "tag:inbox and tag:unread"))))
679 (when (> (string-to-number cnt) 0)
681 (when (search-forward "inbox" (point-max) t)
682 (let* ((overlays (overlays-in (match-beginning 0) (match-end 0)))
683 (overlay (car overlays)))
685 (overlay-put overlay 'face '((:inherit bold) (:foreground "green")))))))))))
686 (add-hook 'notmuch-hello-refresh-hook 'color-inbox-if-unread)
688 ## Linking to notmuch messages and threads from the Circe IRC client
690 [Circe](https://github.com/jorgenschaefer/circe/wiki) is an IRC client for emacs.
691 To have clickable buttons for notmuch messages and threads, add the following to
692 `lui-buttons-list` (using, e.g. M-x customize-variable)
694 ("\\(?:id\\|mid\\|thread\\):[0-9A-Za-z][0-9A-Za-z.@-]*" 0 notmuch-show 0)
696 If you have notmuch-pick installed, it works fine for this as well.
698 ## Linking to notmuch messages from org-mode
700 Support for linking to notmuch messages is distributed with org-mode,
701 but as a contrib file, so you might have to work a bit to load it.
703 In Debian and derivatives,
705 (add-to-list 'load-path "/usr/share/org-mode/lisp")
709 (require 'org-notmuch)
711 In general it is nice to have a key for org-links (not just for notmuch). For example
713 (define-key global-map "\C-cl" 'org-store-link)
