Org also
recognizes macro references in keywords, such as ‘CAPTION’, ‘TITLE’,
‘AUTHOR’, ‘DATE’, and for some back-end specific export options.
How do I discover what those back end specific options are?
Also, for various elements (e.g. begin_src emacs-lisp, begin_export html, etc...) how do I discover what the acceptable keywords are, preferably without only having to go thru the manual pages?
TIA,
