I just tried to export a single subtree from an org document to a PDF file:
1) Type C-c C-e [org-export-dispatch] 2) C-s to narrow to subtree 3) l -> o to export to PDF via LaTeX However, instead of exporting the portion of the file I want, I get the error message Undefined Org macro: newline; aborting That macro is defined in a setup file that is #+included at the top of the file, so exporting the entire file works fine. I assume the problem is that when I export only one subtree, the setup file is not #+included, and I can see it sort of makes sense, but it would be nice if there were an option to include one or more lines from the preamble when exporting just a subtree, since otherwise exporting a subtree doesn’t actually work! Is there a simple way to do this? Thanks.
