KOReader: reassign buttons on Libra H2O

Hello!

I'm sorry if this came up before - I used the search function, but to no avail. I've been using KOReader on Libra H2O, and it's been great! But I'd like to ask something - is there a way to reassign the physical buttons on Libra to always flip to the next page no matter what? I know you can invert their functions, so that the top button turns the page forward, while the bottom one returns to the previous page, but I want both of them to go forward at the same time, no matter the rotation of the device. Would that be possible?

And while we're at it, I guess I might as well ask something else - is there a way to configure each margin individually? Namely, I set all the margins to the minimum in the bottom menu, but the right margin still has some empty space left in it for some reason. Here's a link to a photo:

This hasn't actually been happening to every book I read - some look totally fine, and the text occupies the entire page with no margins left. Could this possibly be a book's fault?

For instance, compare with this image, where there's no empty space to the right. To my knowledge, I haven't changed any margin-related options between taking these two photos:

Yep, the margin issue is most likely wonky CSS somewhere in the book.

FWIW, my American Gods copy is just fine, but then it was originally a Kindle purchase for the anniversary re-release, so it's been through Calibre a couple times .

EDIT: Actually, nope, on my Kobos it's this one. (I, err, may have *quite* a few copies of American Gods lying around, including a couple good old mmpb ).

As for the buttons, something like this should do the trick: https://github.com/koreader/koreader/wiki/Keymapping

NiLuJe, you're nothing short of a hero! It seems that Libra uses the same codes for buttons as Forma (which makes sense), so it only took the following command to map both buttons to always turn forward:

Code:
return {
            [193] = "RPgFwd",
            [194] = "RPgFwd",
 }
(And inverting them in the menu of KOReader produces the reverse effect.)

And thanks for sharing your experience with American Gods - glad to know it's not KOReader-related. It's my first acquaintance with Neil Gaiman (other than Good Omens), and I'm having a blast with it!

Thank you for your time and enjoy your day!

Hi guys, is it a way to have assigned both physical keys to forward page, but to have it funcionaly in both screen orientations? Now when I assign both keys to forward page it works properly in right mode hand, but when I have left hand side mode then keys are switching the page back :/

No without a patch. Some actions , like page forward and page back, are mapped according to current device rotation. See https://github.com/koreader/koreader....lua#L170-L175

Maybe we can add a setting to ignore remapping keys based on rotation?. I'm not sure what NiLuJe thinks.

IIRC, this is also vaguely broken on the reMarkable because no-one actually cared enough to fix it, FWIW ;p.

Change https://github.com/koreader/koreader....lua#L170-L175

On your device it will be placed on /mnt/onboard/.adds/koreader/frontend/device/input.lua

You just need to change a single action. Asumming you asigned both keys to "LPgFwd"

Instead of
Code:
LPgFwd = "LPgBack"
You need
Code:
LPgFwd = "LPgFwd"
Remember to apply the same change after each update.

Hey pazos,

I'm attempting to do just what you suggest:

But I don't know how to find input.lua on my device (Tolino Vision 5). Using adb shell, there seems to be 'No such file or directory'.

I'm sure this is me being dense--could you please point me in the right direction in order to access files such as input.lua on my device?

Instructions on this thread are specific for kobo users.

You can do the same on android if your device is rooted. Just replace /mnt/onboard/.adds/koreader with /data/data/org.koreader.launcher/files, the rest of the path is the same.
