Confirming this affects more than just numpad Enter. I'm also seeing issues with the AskUserQuestion "Other" text input - when typing custom text in the free-form input option, it advances/submits after typing just a single character.

Environment:

• Claude Code: 2.1.x
• Terminal: Ghostty
• Platform: macOS (Darwin 25.2.0)

Workaround that fixed both issues:

Add these keybinds to ~/.config/ghostty/config:

keybind = enter=text:\r
keybind = shift+enter=text:\x1b\r
keybind = shift+space=text:\x20
keybind = kp_enter=text:\r

This forces Ghostty to send legacy terminal escape sequences instead of Kitty protocol sequences for these keys. After adding these and restarting Ghostty, both numpad Enter and custom text input work correctly.

This should be fixed on the latest version.
