sandbox_write_text
Replace a chapter's whole Markdown source with new text, given here (markdown) or read from a Markdown file (file, as the Manuscript panel's import does). For a change to part of a chapter, sandbox_edit_text keeps the rest untouched; a Word document goes through sandbox_import_word. The text it replaces comes back with sandbox_undo_text.
