## Keyboard Customisation

### AltGr+P → `'` (apostrophe) remap

The default Slovak (`sk`) xkb layout inherits `þ` on AltGr+P from the `latin` include. Fixed via a custom xkb user variant.

**Files:**

- `~/.config/xkb/symbols/sk` — custom variant file (named `sk`, not `sk_custom`, because libxkbcommon looks up variants by layout filename)
- `~/.config/xkb/rules/evdev.xml` — local copy of system evdev.xml with `sk_custom` variant registered
- `~/.config/xkb/rules/evdev` — local copy of system evdev rules file
- `~/.config/kxkbrc` — KDE keyboard config pointing to `LayoutList=sk`, `VariantList=sk_custom`

**`~/.config/xkb/symbols/sk` content:**

```
partial alphanumeric_keys
xkb_symbols "sk_custom" {
    include "sk(basic)"
    key <AD10> { [ p, P, apostrophe, NoSymbol ] };
};
```

**Gotchas:**
- `setxkbmap` and `XKB_CONFIG_ROOT` do not work on Wayland — changes must go through `~/.config/xkb/`
- The symbols file must be named after the layout (`sk`), not the variant (`sk_custom`) — libxkbcommon looks up variants inside the layout file
- `include "sk"` causes infinite recursion when the file is named `sk` — use `include "sk(basic)"` instead
- KDE reads `~/.config/xkb/`, not `~/.xkb/`
- keyd was tested but doesn't work cleanly with non-US layouts on Wayland without switching the display server to US layout
