Pages: find and replace multiple Replace page break in Pages
I have several Pages (6.2) docs (converted PDFs) with many unwanted page breaks. But - despite reading about 10 answers to similar questions online - I can't work out how to Find / Replace page breaks in Pages! Several answers seem to indicate that you can Show Invisibles, select a Page Break, and then paste that into the Find field. Well, I can't. I can select (highlight) a page break, but it won't paste. And I can't do the obvious thing, which is to insert a page break into the find field. Nor is there any menu for selecting hidden characters within the find/replace interface, as far as I can see.
As an aside, I love Pages on the whole but this side of the program seems bizarre to me - this sort of thing should be basic, intuitive, and obvious, and it isn't.
