Shift+Enter can't insert a newline

Finde den Ink-Render-Aufruf und untersuche, wie der Lebenszyklus der Terminaleingabe behandelt wird; das Issue nennt die Aktivierung von kittyKeyboard und den vorhandenen Parser isNewlineShortcutKey als relevante Einstiegspunkte. Aktiviere das kitty-Tastaturprotokoll, bewahre das Verhalten von Ctrl+J und Enter und behandle die Protokollbereinigung beim Beenden und bei Signalen. Verifiziere dies mit cmd in einem Terminal mit kitty-Protokoll unter Verwendung von AAA, Shift+Enter, BBB und Enter und bestätige, dass Ctrl+J weiterhin einen Zeilenumbruch einfügt.

Summary

Shift+Enter submits the prompt instead of inserting a newline, so multi-line prompts are impossible without knowing the undocumented Ctrl+J fallback. The input parser already accepts the enhanced Shift+Enter sequences; the app never activates the kitty keyboard protocol, so capable terminals keep sending a bare CR.

Expected Behavior

Enter submits, Shift+Enter inserts a newline — as the help panel states: "Shift+Enter / Alt+Enter → Insert a newline".  tui.input.newLine  already defaults to ["shift+enter","ctrl+j"] .

Actual Behavior

Shift+Enter behaves exactly like Enter: the prompt submits immediately. Only Ctrl+J inserts a newline.

Cause: the build bundles  ink  7.1.0 but never sets  kittyKeyboard , and contains no protocol push ( \x1b[>1u ). The parser does accept the encoded sequence ( isNewlineShortcutKey  handles  \x1b[13;2u ,  \x1b[27;2;13~  and peers), so only the activation is missing.

Steps to reproduce the issue

1. Run  cmd  in a kitty-protocol terminal (WezTerm here; it needs  enable_kitty_keyboard = true ).
2. Type  AAA , press Shift+Enter, type  BBB , press Enter.
3. Observed: submits on Shift+Enter, only  AAA  is sent. Expected: two lines.

Pushing  \x1b[>1u  around the binary from a zsh wrapper makes Shift+Enter send  \x1b[13;2u  and work correctly, which confirms the terminal and parser are fine.

Fix prompt (optional)

Enable the kitty keyboard protocol in the Ink render call — Ink supports it since 6.7.0:

render(<App />, { kittyKeyboard: { mode: 'enabled' } });

Use  'enabled' , not  'auto'  (auto-detection fails under tmux). Pop with  \x1b[<u  on exit and in signal handlers. The parser already handles the sequences, so no parser change is needed. Keep Ctrl+J as the universal fallback and document that WezTerm needs  enable_kitty_keyboard = true .

Check:  cmd  →  AAA  → Shift+Enter →  BBB  → Enter must show two lines; Ctrl+J must still insert a newline and Enter must still submit.
