+----------------

+Each notmuch buffer supporting tagging operations (i.e buffers in
+:any:`notmuch-show`, :any:`notmuch-search`, :any:`notmuch-tree`, and
+:any:`notmuch-unthreaded` mode) keeps a local stack of tagging
+operations. These can be undone via ``notmuch-tag-undo``. By default
+this is bound to the usual Emacs keys for undo.
