sandbox_go_to_page
Show a page of the book in the viewer on screen: the next or previous one, the first or the last, a page by the number printed on it or by its position in a chapter, the first page of a chapter, the page where a passage of the text is set (which also places the selection there when the Manuscript panel is open), or the page where a resource, a heading's id, an anchor or a footnote's note is set (anchor: where a link to it leads). The EPUB reader goes by its own file: position is a document of its reading order (a page, in the fixed layout), contents an entry of its table of contents. Give one way of naming the page per call.
Page: /en/sandbox
