I want to be able to attach files to a sub-tree from a Dired buffer. The org-mode manual gives instructions on how to do this in the link below:
At the bottom of the article they have two pieces of code that one is to insert into one's init file to get this to work. However, neither set of lines work. I have tried them and they generate errors.
My goal is to be able to attach multiple files at one time to my org headlines. At present I use C-c C-a m which attaches a file at a time.
