 * Org
-  I use a couple non-standard bits and pieces, but not a whole
-  bunch. I really like the =<s= to insert a source block thing (which
-  was deprecated); =org-tempo= brings that back.
+** Code and Quote block shortcuts
+   I am a big fan of using =<s= for source blocks and =<q= for quotes;
+   these are enabled by the =org-tempo= module, which is included in
+   =org= but not loaded by default.
 
    #+begin_src emacs-lisp
-    (use-package org
-      :config
-      (require 'org-tempo))
+     (use-package org :config (require 'org-tempo))
    #+end_src
 
+   However, I have recently discovered, much to my despair, that these
+   shortcuts do not work if there are tabs in the line ahead of them!
+   Quite ridiculous.  Easily worked around, however; I am going to
+   ensure that spaces are used for indentation when in org mode by
+   setting [[help:indent-tabs-mode][indent-tabs-mode]] to nil in a hook:
+
+   #+begin_src emacs-lisp
+     (add-hook 'org-mode-hook (lambda () (setq indent-tabs-mode nil)))
+   #+end_src
+
+** Keybindings
    A keybinding to add a new heading is super useful
