sandbox_undo_text

Take back the last change when it is an edit to a chapter's text, or with redo put back the last one taken back. The Sandbox keeps one history of text and design, in the order the changes were made (the one Cmd/Ctrl+Z undoes): text typed in the Manuscript editor, the edits the reader made on the previews (a comic panel resized, a frame's text), and what sandbox_write_text, sandbox_edit_text and sandbox_import_word (into a chapter) changed, one call at a time, latest first whatever the chapter. When the last change was to the design it is refused, with the settings it touched: sandbox_undo takes back the last change whatever it is. Chapters added, removed, split, merged or moved, resources and fonts are not in the history, and opening another book empties it. An edit is taken back over the changes made to the chapter since by other means, which stay. The history is kept for this visit: it is empty after the page is reloaded.
