Publish manuscript prepares files for the entire manuscript, even when you select only audio. Choose the output formats, then Publish. Publication ready means the files are ready to download, not that your work has been distributed publicly.
Include in offers Print & audio, Print only, Audio only, and Neither. These choices control the existing outputs; they do not add a new file format. Inline math keeps its print-only restrictions. Neither can hide a heading from output without removing its section boundary.
Open Job Status for the account, select the job, and use Files or Downloads. Available formats depend on what that job produced. Listening and publishing share this history; project exports remain separate export jobs.
