Permission prompt: number-key shortcuts (1/2/3/4) for Allow once / Always allow / Deny

[wesleymatos-bot]

The tool-approval dialog (Allow once / Always allow in this project / Deny and tell ZCode why / Deny) is navigated with Up/Down + Enter only. For keyboard-driven users this is the slowest interaction in the TUI — approval prompts interrupt flow constantly, and hitting Up-Up-Enter every time adds up.

Proposal: number the options (1 = Allow once, 2 = Always allow, 3 = Deny and tell..., 4 = Deny) and let pressing the digit select+confirm in one keystroke, like Claude Code's permission prompts do. Up/Down + Enter can stay as-is for discoverability.

Why it matters: when driving multiple zcode sessions in tmux (fleet workflows), approval dialogs are the main context-switch cost. Single-keystroke approval would cut a 3-keystroke interaction to 1.

Happy to submit a PR if you point me at the dialog component (looks like it's in packages/zcode-tui).

Author here — took my own advice and dug into the source. The dialog lives in packages/zcode-tui/src/components/tool-approval.ts (renders from the permission request's allow/alwaysAllow/deny action list built in the approval controller).

The fix is small: each option row already renders in a fixed order, so register a digit keybinding per option in the dialog's key handler and treat it as select+confirm. Sketch of the change:

```ts
// tool-approval.ts — inside the key handler
if (/^[1-9]$/.test(key.name)) {
const idx = parseInt(key.name, 10) - 1;
if (idx < this.options.length) {
this.selectedIndex = idx;
this.confirm(); // same path Enter takes
return;
}
}
```

Rendering side, prefix each label with its number:

```ts
label: `${i + 1}. ${option.label}`
```

Keeps Up/Down + Enter working unchanged, adds 1-keystroke confirm. Max 9 options covers every current dialog.

I can open a PR with this + a test if you want it — just confirm the component file is the right place (I was reading the published bundle, not the repo internals).

Update: opened PR #136 with the implementation + tests. Closing the loop on my earlier comment — the dialog component is packages/zcode-tui/src/choice-dialog.ts (ChoiceDialog.handleInput + choose()), and the fix works entirely through pi-tui's public SelectList API (setSelectedIndex / getSelectedItem / onSelect), no upstream changes needed.
