Unable to insert a new line in Claude Code terminal session on macOS using Command+Enter

[sebarys]

Description

When using Claude Code in a terminal session on macOS, it's not possible to insert a new line into the prompt using the standard Command + Enter shortcut.

I've only reproduced this on macOS, as I haven't tested other operating systems.

Steps to reproduce

1. Run:

   sandcat attach

2. Start Claude Code:

   claude-yolo

3. Try to enter a multi-line prompt by pressing Command + Enter to insert a new line.

Expected behavior

Pressing Command + Enter inserts a new line, allowing the user to compose a multi-line prompt.

Actual behavior

Command + Enter does not insert a new line (just Enter is detected), making it impossible to compose a multi-line prompt using this shortcut.

Environment

• OS: macOS
• Reproduced only on macOS (other operating systems have not been tested).
