+Adding three new conveneince functions:\r
+\r
+notmuch-show-next-open-message-or-pop\r
+notmuch-show-next-thread\r
+notmuch-show-previous-thread\r
+\r
+While these are not currently bound to any keys, I have found them to\r
+be very useful for constructing custom key bindings outside of what\r
+notmuch provides by default.  For example:\r
+\r
+(define-key notmuch-show-mode-map "a"\r
+  (lambda ()\r
+    "archive current message and advance"\r
+    (interactive)\r
+    (notmuch-show-remove-tag "inbox")\r
+    (notmuch-show-next-open-message-or-pop)))\r
+(define-key notmuch-show-mode-map "N" 'notmuch-show-next-thread)\r
+(define-key notmuch-show-mode-map "P" 'notmuch-show-previous-thread)\r
