evince: disable all keyboard shortcuts except PageDown, PageUp

I have file ~/.config/evince/accels but it is empty. what is the syntax for disabling the idiotic default keyboard shortcuts? Can I perhaps "dump" the current shorcuts, and then edit? I constantly lose my position on page by accidentally pressing some key. I just want to keep PageDown and PageUp so that I can scroll the pages. I am using Evince 43 on Debian
