Score editor: how to add page nuber and adjust the font size for Chords?

Anybody here can tell to how to add page numbers in the page view of score editor for Cubase pro 9.5?

And, if toggle the “advanced layout” to show the “chord track markers”, how to adjust the size of the markers. They are too large now. I attached a picture for reference.

Don’t know about the marker size.

But for page numbers

For chord display adjustments go to Score Settings>Project tab>Chord Symbols.

Thank you so much.
