cmux-keyboard-shortcuts

# cmux-keyboard-shortcuts Turn a user's workflow preferences into cmux shortcut bindings in `~/.config/cmux/cmux.json`: guide, propose compact templates, apply the selected changes, and confirm the config parses with recognized keys. ## Contributor rule: adding a new shortcut Every new cmux-owned keyboard shortcut must be added to `Sources/KeyboardShortcutSettings.swift`, visible and editable in Settings > Keyboard Shortcuts, supported as `shortcuts.bindings.<actionId>` in `~/.config/cmux/cmux.json`, and documented in `web/app/[locale]/(landing)/docs/keyboard-shortcuts/page.tsx` and the configuration docs. All four, not a subset. ## Prerequisites - Work from a cmux checkout or worktree root when possible. - Use `skills/cmux-settings/scripts/cmux-settings` for every read/write. It reads JSONC, writes atomically, and validates JSON plus recognized settings keys. - Action IDs: `skills/cmux-settings/references/shortcut-actions.md`. Current defaults: `web/data/cmux-shortcuts.ts` or `Sources/KeyboardShortcutSettings.swift`. ```bash if [[ -z "${CMUX_SETTINGS:-}" ]]; then root="$(git rev-parse --show-toplevel 2>/dev/null || pwd)" for candidate in \ "$root/skills/cmux-settings/scripts/cmux-settings" \ "${CODEX_HOME:-$HOME/.codex}/skills/cmux-settings/scripts/cmux-settings" \ "$HOME/.agents/skills/cmux-settings/scripts/cmux-settings"; do [[ -x "$candidate" ]] && CMUX_SETTINGS="$candidate" && break done [[ -n "${CMUX_SETTINGS:-}" ]] || { echo "cmux-sett...
