This is a standard syntax for adding values to a property. From the info manual: If you want to add to the value of an existing property, append a ‘+’ to the property name. The following results in the property ‘var’ having the value ‘foo=1 bar=2’. #+PROPERTY: var foo=1 #+PROPERTY: var+ bar=2 -- : Eric S Fraga via Emacs 28.0.50, Org release_9.3.7-636-gaa32f6
