+** Pulse line
+   Set some options for pulsing:
+
+   #+begin_src emacs-lisp
+     (setq pulse-iterations 10)
+     (setq pulse-delay 0.05)
+   #+end_src

+       "Pulse the current line."

+   Run it in certain cases: scrolling up/down, recentering, switching windows.
+   'dolist' binds 'command' to each value in the list in turn, and runs the body.
+   'advice-add' makes the pulse-line function run after 'command'.

 * Misc settings
 ** Enable all commands
    By default, Emacs disables some commands.
