ctrl + enter does not add a new page as specified in the help. How then can I insert a new page?
Well Ctrl + Enter does add a new page on my system. If this is not working an alternative approach is to select INSERT > MANUAL BREAK > PAGE BREAK. This will give you a new page. The menu then allows you to select the PAGE STYLE for the next page and also to select the NEW PAGE NUMBER is this is required.
If you still have a problem, indicate the LibO version and operating system in case there is a system specific problem.
