[BUG] Linux/Ubuntu Terminal Newline mis-labeled ('Alt+Enter' would be correct)

Environment

• Platform (select one):
• [x] Anthropic API
• [ ] AWS Bedrock
• [ ] Google Vertex AI
• [ ] Other: <!-- specify -->
• Claude CLI version: 1.0.80 (Claude Code)
• Operating System: Ubuntu 24.04

Bug Description

The tips and /terminal-setup command mention Shift+Enter instead of Alt+Enter.
First one doesn't work, only Alt+Enter.

Steps to Reproduce

1. Start Claude Code
2. try Shift + Enter
3. Will not produce Newline!

Expected Behavior

Any documentation/tips should mention the correct keybinding and the /terminal-setup should set the correct keybinding, NOT Shift+Enter, but Alt+Enter.

Actual Behavior

Incorrectly labeled.

Additional Context

SOLUTION: Just use Alt + Enter for newlines
