Photo Advancement with Arrow Keys instead of Mouse Wheel

Help & Support
1

Is there a way to advance photos using the arrow keys instead of the mouse wheel while using the photo viewer? If there is I can't find a setting for it.

Space/Backspace and Page Down/Page Up are the default pairs for next/prev image.

If you're using the Opus 12 public beta then the viewer's hotkeys are full configurable via Customize to add more alternatives or redefine the existing keys:
