I saw this in a message - Read the manual, page 155. - . I can't find any thing with a page number. I thought I would just play new user/customer. Go to official Help and you are directed to the official Wiki. In my opinion the Wiki is not well structured as a source of help for a specific product. It seems to be best for fulsome descriptions of specific items. It is to easy to click on the wrong thing and end up in a dead end. So I have never found Page-155.
