   This property is retrieved with inheritance, meaning that it can be
   set in any ancestor entries or at the top of the file with
   <code>#+PROPERTY: ANKI_FORMAT nil</code>, it's also possible to
   override an outer level nil format with <code>:ANKI_FORMAT: t</code>.

* Is there a shorter way to write notes?
  :PROPERTIES:

** Back

   Yes, like this one, Front is missing, ~anki-editor~ will use note
   heading as Front.  This is neat as sometimes it's verbose to repeat
   the same content in note heading and first field.

   This works for all note types, just make one field absent and
   ~anki-editor~ will use note heading as that missing field.
