+* Falling back to WM to switch windows
+
+  Emacs and any window manager have a difference op opinion on what
+  windows are. It doesn't have to matter, Emacs can manage its windows
+  and stumpwm can do the rest. When moving around with ~windmove~ and it
+  finds that there's no way to move in that direction, let stumpwm do
+  it.
+
+  First we have to know where the stumpish program is. SLIME could
+  also be used, but calling stumpish might be easier for now.
+
+  #+BEGIN_SRC emacs-lisp
+    (defvar init-stumpish-program
+      (expand-file-name
+       "~/.local/share/quicklisp/local-projects/stumpwm/contrib/stumpish")
+      "The location of the stumpish executable.")
+  #+END_SRC
+
+  Now that we know that, we should have an easy way to send stuff to
+  it.
+
+  #+BEGIN_SRC emacs-lisp
+    (defun stumpwm-command (cmd)
+      "Execute CMD in stumpwm."
+      (call-process init-stumpish-program nil nil nil cmd))
+  #+END_SRC
+
+  And then we can advise =windmove-do-window-select=, so that when it
+  finds there are no more windows to move to, it asks stumpwm to move
+  in the same direction.
+
+  #+BEGIN_SRC emacs-lisp
+    (defadvice windmove-do-window-select
+      (around init-windmove-stumpwm activate)
+      "If no window can be moved to, move stumpwm."
+      (condition-case err
+          ad-do-it
+        (error (stumpwm-command (format "move-focus %s" (ad-get-arg 0))))))
+  #+END_SRC
+
+  Now, whenever I try to move out of my Emacs windows, it just moves
+  to the next X11 window, whatever it might be. My stumpwm config has
+  a matching command that checks to see if the current window is
+  Emacs, and if so sends the ~S-<direction>~ key to Emacs, which in turn
+  calls stumpwm when it can't (getting a little crazy here).
+
+  I also wrote a simplistic macro to execute some stumpwm lisp in
+  Emacs.
+
+  #+BEGIN_SRC emacs-lisp
+    (defmacro stumpwm (&rest body)
+      "Execute BODY in stumpwm."
+      (declare (indent 0))
+      `(call-process init-stumpish-program nil nil nil
+                     ,(format "eval '%S'" `(progn ,@body))))
+  #+END_SRC
+
+  Which is pretty much the same as my =elisp= macro in my stumpwm
+  config.
