I have started a new document. First page is fine. How do create page 2? Google says to type Ctrl+Enter but that does nothing. I looked at “Insert” but I see nothing about adding a page.
Just keep typing. The first page will overflow onto a new (second) page, and so on. You can go back later and Insert a Page Break wherever you want, throughout your document. That’s what I do.
Not type, press the keys Ctrl+Enter
Using the menu click Insert > Page Break.
If you need another page style then click Insert > More breaks > Manual break and in the dialogue select the new page style and choose the page numbering, Continue or Restart, you need.
Generally, just follow @ve3oat advice and Writer will add pages when needed.
