docs: add a keybindings reference covering Sway/tmux/foot/zsh
Document every configured shortcut in lyrathorpe/home/KEYBINDINGS.md, compiled from the rendered configs (so it includes the home-manager Sway module defaults alongside the custom binds and modes), and link it from the top-level README. Notes the Dvorak keysym caveat and the laptop-only brightness keys. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

# Keybindings reference
|
||||
|
||||
Every keyboard shortcut configured across this desktop, and where it is defined.
|
||||
Everything here is managed declaratively through Nix — edit the listed file and
|
||||
rebuild, never the generated dotfiles.
|
||||
|
||||
| Area | Defined in |
|
||||
| --- | --- |
|
||||
| Sway (compositor) | [`sway.nix`](./sway.nix) `config.keybindings` + `config.modes`, plus the home-manager Sway module's built-in defaults |
|
||||
| tmux | [`shell.nix`](./shell.nix) `programs.tmux` |
|
||||
| zsh line editor | [`shell.nix`](./shell.nix) `programs.zsh.historySubstringSearch` |
|
||||
| foot (terminal) | foot package defaults — only colours are themed (in `sway.nix`) |
|
||||
|
||||
**Conventions**
|
||||
|
||||
- **Super** is the `Mod4` / logo (Windows/Command) key; **Alt** is `Mod1`.
|
||||
- Letter keys are **keysyms** (the character produced), not physical positions.
|
||||
The keyboard is **Dvorak** (`us`/`dvorak`), so e.g. "Super+s" is whatever key
|
||||
types `s` in Dvorak.
|
||||
- Shortcuts apply to every Sway host (MBP, T400, Mac Pro); brightness keys are
|
||||
laptop-only, as noted.
