This may seem a stupid question but indulge me: when I add a page break InDesign is only showing me the very top of the text frame on the page the cursor has moved to. How do I get InDesign to honour the 'Fit Page to Window' option when I add page breaks? Do I really have to keep hitting command-0?
Yeah, the contents of your document have nothing to do with the view window.
(There seems to be little connection between what you do in a document and what InDesign thinks is the best view to show it. It's as annoying as the Page Up/Down keys that by default scroll screens, rather than pages.)
It does like to go exactly to the first line of the next page. It's not very intuitive.
However, you can hold down Alt and scroll the page up.
Or while holding alt - click and hold anywhere on the page. It will zoom out. Move the red box where you want to Zoom to, then release the mouse.
Or you could press Return a few times then delete the returns.
