+The Emacs client can generally display HTML messages inline using one of the

-The first option is theorically better, because it can generate
-strings formatted for emacs and do whatever you want, e.g., substitute
-text inside &lt;b&gt; tags for bold text in the buffer. The library, however
-is still in a very early development phase and cannot yet process
-properly many elements, like tables and <style> directives, and even
-the generated text is often poorly formatted.
-
-Among the available browsers, w3m seems to do a better job converting
-the html, and if you have the w3m emacs package, you can use it,
-instead of the w3m-standalone, and thus preserve the text formatting.
-
-But if the rendering fails for one reason or another, or if you really
-need to see the graphical presentation of the HTML message, it can be
-useful to display the message in an external viewer, such as a web
-browser. Here's a little script that Keith Packard wrote, which he
-calls `view-html`:
-
-        #!/bin/sh
-        dir=`mktemp -d`
-        trap "rm -r $dir" 0
-        cat "$@" > "$dir"/msg

-        fi

-                exit 0
-            fi
-        done
-
-Save that script somewhere in your `${PATH}`, make it executable,
-and change the invocation of `iceweasel` to any other HTML viewer if
-necessary. Then within the emacs client, press '|' to pipe the
-current message, then type "view-html".
-
-Keith mentions the following caveat, "Note that if iceweasel isn't
-already running, it seems to shut down when the script exits. I

 ## Hiding unread messages in notmuch-show
 
@@ -694,3 +703,50 @@ To have clickable buttons for notmuch messages and threads, add the following to

 If you have notmuch-pick installed, it works fine for this as well.

+## Linking to notmuch messages from org-mode
+
+Support for linking to notmuch messages is distributed with org-mode,
+but as a contrib file, so you might have to work a bit to load it.
+
+In Debian and derivatives,
+
+    (add-to-list 'load-path "/usr/share/org-mode/lisp")
+
+Then
+
+    (require 'org-notmuch)
+
+In general it is nice to have a key for org-links (not just for notmuch). For example
+
+    (define-key global-map "\C-cl" 'org-store-link)
+
+## Viewing diffs in notmuch
+
+The following code allows you to view an inline patch in diff-mode
+directly from notmuch. This means that normal diff-mode commands like
+refine, next hunk etc all work.
+
+    (defun my-notmuch-show-view-as-patch ()
+      "View the the current message as a patch."
+      (interactive)
+      (let* ((id (notmuch-show-get-message-id))
+             (subject (concat "Subject: " (notmuch-show-get-subject) "\n"))
+             (diff-default-read-only t)
+             (buf (get-buffer-create (concat "*notmuch-patch-" id "*")))
+             (map (make-sparse-keymap)))
+        (define-key map "q" 'notmuch-kill-this-buffer)
+        (switch-to-buffer buf)
+        (let ((inhibit-read-only t))
+          (erase-buffer)
+          (insert subject)
+          (insert (notmuch-get-bodypart-internal id 1 nil)))
+        (set-buffer-modified-p nil)
+        (diff-mode)
+        (lexical-let ((new-ro-bind (cons 'buffer-read-only map)))
+                     (add-to-list 'minor-mode-overriding-map-alist new-ro-bind))
+        (goto-char (point-min))))
+
+and then this function needs to bound into the keymap with something like
+
+    (define-key 'notmuch-show-mode-map "D" 'my-notmuch-show-view-as-patch)
