missing navigation shortcuts with no option to define them

When giving a presentation, keyboard navigation is critical (menu and toolbar are not available).
The most important shortcuts (page down and page up) are present,
but the history navigation (back - Alt-Left and forward - Alt-Right) are missing.
This is critical for navigating in-document hyperlinks.
Moreover, one cannot define these shortcuts as custom because they are available only in the toolbar, not the menu
(see https://help.gnome.org/users/evince/stable/shortcuts.html.en).
