Dear all, Is there any way to specify src code switches, e.g. #+begin_src maxima +n -r, via a property for the subtree, as one can do for header arguments? I have taken a look at ob-core.el. I found that the function org-babel-params-from-properties makes use of the variable org-babel-common-header-args-w-values, which defines a list of only header arguments. (Org-mode version 8.0.5) If not via a property, any suggestion (perhaps an in-buffer setting)? Your help is much appreciated. Cheers, Manuel GJT
