[Mac Version] How to work with shortcuts?


has somebody more experience in working with the Mac Version of NM 3.16+? I can’t figure out how I can move between pages using the Page Up/ Page Down key on my keyboard. I’m used to reading thru all documents using this key and it is somehow annoying. And also, can I set a shortcut for a font format “underline” and “italic”?

And can I set somewhere my personal choice of marking colours, I mean I see and use the existing colour palette - but can I set my another colour somewhere?
