Summary

Shift+Enter no longer inserts a newline in pi when running inside Zellij after upgrading pi. It still works correctly outside Zellij.

Environment

• pi: 0.67.3
• zellij: 0.43.1
• terminal outside zellij: works as expected
• custom pi keybindings:

{
  "tui.input.newLine": ["ctrl+j", "shift+enter"],
  "tui.input.submit": ["enter"]
}

Expected behaviour

Inside Zellij, Shift+Enter should insert a newline in the editor.

Actual behaviour

Inside Zellij, Shift+Enter does not insert a newline / behaves like plain Enter.

Reproduction

1. Start zellij
2. Launch pi
3. Type some text in the editor
4. Press Shift+Enter

Observations

• This used to work inside Zellij before upgrading pi.
• It still works outside Zellij.
• pi docs currently say for Zellij: "no extra Zellij config is required" and pi uses modifyOtherKeys mode 2 inside Zellij.

Notes

This looks like a regression in pi’s key handling around Zellij-specific modified Enter detection.
