Volume buttons for nav

[Logicenios]

Hellos,

I would like to be able to open an article and move to the next or previous article with volume buttons. That would also make the articles read.

I think this will bring a more accessible way to read articles fast and make it more tactile.

Finally, I would like to thank the devs for an incredible work!

Also I would like to translate the app in Greek if you could enable it in weblate.

Thanks @Logicenios, I'll think about it. It sounds similar to some other ideas I'd like to make it easier to navigate on eReaders for example.

For translations, I just added an entry for Greek here:

@jocmp Understood, I'm using tt-rss and respective Android client - https://git.tt-rss.org/fox/tt-rss-android.git

Totally unrelated there's also Mihon for manga reading which has the same functionality - https://github.com/mihonapp/mihon

Let me know if this doesn't help - I can at least look up more implementations

[jocmp]

Thanks! Y'know, if you do want to implement this after all, I recommend following Mihon's implementation. Their license is compatible with MIT and I've used their codebase for theming and settings before.

@jocmp well, I can take a stab a this, I have relatively little experience with Android development in general so this might require some hand holding. If you're okay with this then I'll start working on this tomorrow.

[jocmp]

No rush! Feel free to open a PR or ask questions here. I'll take a look at Mihon's implementation too when I get a chance.

Hey @Quintasan, I'm not actively looking to implement this yet, but if you use any other Android apps that are open source, I can take a look to get a feel for the implementation in general.

The email app "Thunderbird" from F-Droid has this feature.

Picked up a Boox Go 7 which out of the box works great with Capy. The device has per-app customizations that can set its side buttons to:

• Page Turning (these seem to be mapped to Pgdn/Pgup)
• Volume keys
• Scrolling (feels like auto touch input or mouse scrolling)

A lot of reader apps (Play Books, KOReader) prompt to hijack volume keys to do page turns - it'd be nice to see this as an option in Capy too. The existing eink tap to scroll corners work well, so I'd figure the volume scroll would perform the same action.

This might be mostly solvable in #1649 by adding page up/page down shortcuts to perform the same action as the eink tap corners. Currently the "page turning" buttons take three presses to do the first scroll action - it seems like it's tabbing through the close button and title element first.

Currently when the device's buttons are set to "scrolling" the up button at the top of an article triggers the "swipe down" gesture configured in Capy, and the down button at the bottom of an article triggers the "swipe up" gesture - which feels a bit backwards, but that's on the implementation of the device's scrolling shortcuts and not Capy.

It feels like the most common sense implementation of pressing volume scrolling/page turning buttons at the top/bottom of the article would be jumping to previous/next articles, but it wouldn't hurt to have these be configurable to trigger next|previous article/full content/open in browser/return to list.

I think my personal ideal setup would be volume/page up at the top of the article triggering opening in browser and volume/page down at the bottom of the article triggering next article.
