Page Up / Down Physical buttons not working with Mokuro HTML

[mashuu99]

Hi! I'm using jidoujisho with Mokuro-generated HTML files on my ereader.
However, the Page up and Page down physical buttons don't work as expected, they don’t trigger any page navigation within the document.

Device info:

Device: Meebook M7 (Android)
Jidoujisho version : 2.8.10

Steps to reproduce:

1. Open a mokuro-generated HTML with jidoujisho.
   

2. Attempt to use physical Page up / Page down buttons.
   

3. Nothing happens (no scrolling or navigation).
   

Expected behavior:
The physical buttons should scroll or navigate through the content as they typically would in a regular HTML file or ebook, like the volume buttons.

It might be helpful to add a checkbox option to enable Page up / down support in the same settings menu as the volume button configuration.

Thanks!

I have honestly never used Mokuro generated html files, but after some digging online, I found something that could potentially fix it:

This post on a WaniKani forum which appears to put all the pages right after the other and allow for scrolling

I will attempt to try this myself, however take all of this with a grain of salt because I have neither an e reader with physical buttons or used Mokuro generated html

Hey, thanks for your tips!
Well, it's one of the available solutions. I haven’t tried it myself, but it should work.

I found a workaround using the app Key Mapper, which lets you map a "touch screen" event to physical button presses while using Jidoujisho.

Everything works flawlessly with it (just make sure to disable volume page turning in Jidoujisho to avoid some bugs).

Also, I confirmed that the bug is probably not caused by the e-reader itself. I have the option to set what the physical buttons do (volume control, page up/down, arrow keys, scrolling), but even when set to volume control, it doesn’t work properly with Jidoujisho (only one button works, and it skips two pages at a time)

I’ve included some screenshots in case anyone wants to use Jidoujisho in a similar setup :)
