One of the things I like about the Mimas is the physical page turn (actually volume) buttons, which work great in the built-in reader and also in e.g. Pocket and Moon+ Reader. Since they are actually volume buttons though, they
don't work in other apps, and e.g. I wanted to use them for page down in Kiwix or an internet browser (but the only internet browser I found that supported navigation with the volume buttons was Dolphin and I preferred Firefox). I hardly need to change volume on the device at all, so wanted to remap these to page up and down - and, after trying all sorts, I finally got it working and thought I'd share, in case this is useful for anyone else.
What worked for me is to use
Button Mapper. Caveats:
- additional setup required. Because no-one has (yet!) managed to root the Mimas, you need to do an additional setup step using USB debugging - see https://setup.buttonmapper.app. You also need to repeat this each time the device is rebooted - which is a bit clunky, but I can live with for the moment.
- you need to buy the Pro version of the app to remap buttons to send key codes, but for the cost of a cup of coffee, it was worth it for me.
- The app isn't designed for e-ink. I found I could just about see what was going on with the dark grey on light grey lettering if I cranked up the light to maximum brightness. Your mileage (and eyesight) may vary..
If you do go ahead and install (and pay for) Button Mapper, you can then remap the volume buttons. I remapped:
- volume up: single tap to keycode 92
- volume down: single tap to keycode 93
... and now I can use the 'page up/down' buttons more or less everywhere! Well at least in all the software I'm using: Firefox, Kiwix, Calibre Companion, Pocket, Moon+ Reader and the Boyue PDF reader. So far so good
