Absolutely - but this has been (unfortunately!!!!!!!) be deprecated: Quoted from the manual [1] : ,---- | [1] The deprecated syntax for default header argument properties, using | the name of the header argument as a property name directly, evaluates | the property as seen by the corresponding source block definition. This | behavior has been kept for backwards compatibility. `---- I was using this deprecated behavior and I was *very* happy with it, but I am trying to adjust to the new syntax. So how can I use the new syntax? Rainer Footnotes: [1] http://orgmode.org/manual/Header-arguments-in-Org-mode-properties.html#Header-arguments-in-Org-mode-properties -- Rainer M.
