Still can not find keep with next or what is meant by
Set your ACTION and DIALOG styles to keep lines together but not keep with next.

In my supplied doc I found the Keep with next by format, Paragraph, Lines and page breaks.
I ticked Keep with next. I tried to get the line "Well she does come across a bit scary." to stay on the first page but it refuses.
I also have a window Orphan box ticked. Don't understand this.
