layouts/latn_bone.xml: improve

[quantenzitrone]

new syntax: n/s/e/w/ne/nw/se/sw instead of key{1..8}

Some keys were missing keys according to the tests, this adds them similarly to latn_neo2.
Only switch_backward didn't fit (because of the 0 at the bottom of the spacebar).

I also added a \ in front of the @, not sure if that is necessary, but it is part of the escape character documentation.

Thanks!

switch_backward and switch_forward are extremely important keys as they allow between layouts.
The bottom row is similar to the default one except for some keys added in this PR. To avoid maintaining this in the future and missing new features, what do you think of removing the custom bottom row in this layout ? The cost is to move 0 elsewhere.

[quantenzitrone]

I've always been switching keyboard with change_method in the upper right of the Fn key.

[quantenzitrone]

Oh I realize its for switching the internal layout.
Gonna fix this later.
At least switch_forward should be on the space bar.

[quantenzitrone]

Ok now only switch_backward is missing.
Which may be annoying if you have more than 2 different keyboard layouts to switch between.
But switching is possible.

I could put the 0 on se like the other numbers, but I think it should remain on space.
I think I had problems with corner keys on the spacebar due to the length, but I could try it.

[quantenzitrone]

I have an idea.
Is it be possible to combine accent_circonflex and superscript with a modmap?

[quantenzitrone]

Do we have these diacritical marks?

I have no idea why neo people put these on the bone layout. They are probably not needed, especially not on the latin layer.

I could put the 0 on se like the other numbers, but I think it should remain on space.

That means having to maintain the layout more often and having inconsistent placement for important keys.

Is it be possible to combine accent_circonflex and superscript with a modmap?

That's currently only possible by modifying the app to add this combinaison as a new diacritic.

Do we have these diacritical marks?

We don't have Rough and Smooth breathing I believe but they could be added if necessary.

[quantenzitrone]

Nah I think rough and smooth breathing are not necessary.
Not even computer neo layouts have a use for rough breathing, according to the documentation the key is completely useless.

[quantenzitrone]

Would you accept if I add neo specific modifiers (diacritics)?
They could be used for neo2 and bone as well as other neo variants that may be added in the future: neoqwert{z,y}, mine, noted.
While they are not super needed, they are a neat feature of neo layouts.

[Julow]

Adding neo specific diacritics and compose sequences to the app is fine! It's possible to add a new compose key that is either a pre-applied sequence or an entirely different set of sequences.

[quantenzitrone]

If you want, you can merge this like this.
I'm currently working on improving (completing) the current diacritics modifiers, so I can combine some of them in the way neo does it for the neo specific modifiers.
I opened another pr #770 because it got out of scope of this pr.
