Chris Maiorana has a very nice video up on how he configured Org mode to export to standard manuscript format. The standard manuscript format is the format that’s used—or at least used to be used—for submitting manuscripts for novels and short stories. Most of us have no use for that, of course, but the video is still useful because it shows us how to customize the output that Org generates when you export to LaTeX.
Most of the configuration involves the org-latex-classes templates, which are pretty easy to figure out. You can specify the document class and what LaTeX the Org headers map into. The other configuration is making some global changes to prevent Org from adding superfluous information to the LaTeX output.
See the video for the details. There’s also a link to his configuration so you don’t have worry about writing it down. The video is only 8 minutes, 40 seconds so it should be easy to find time for it.
