Incorrect keyboard shortcut documentation for newline on macOS

Description

The help/settings documentation incorrectly states that Shift + Enter creates a newline in the command prompt on macOS.

Current Behavior

• Documentation shows: Shift + Enter for newline
• Actual behavior: Shift + Enter submits the command (same as just pressing Enter)

Expected Behavior

• The correct keyboard shortcut for creating a newline on macOS is Option + Enter

Platform

• OS: macOS (Darwin 25.2.0)
• Claude Code CLI

Steps to Reproduce

1. Open Claude Code CLI on macOS
2. Check help (?) settings for newline keyboard shortcut
3. Try using Shift + Enter - it submits the command instead of creating a newline
4. Use Option + Enter - this correctly creates a newline

Suggested Fix

Update the documentation/help settings to show the correct keyboard shortcut for macOS:

• macOS: Option + Enter
• Not: Shift + Enter
