Bug Description

When trying to login with Claude Code on WSL Ubuntu (Windows),
the authentication code received from the browser cannot be
pasted into the "Paste code here if prompted >" field.

Environment

• OS: Windows with WSL Ubuntu
• Terminal: Windows Terminal / PowerShell with WSL
• Claude Code version: latest

Steps to Reproduce

1. Run /login
2. Select option 2 (Anthropic Console account)
3. Copy URL, open in browser
4. Browser returns a long authentication code
5. Try to paste the code in the terminal field

Problem

• Ctrl+V does not work
• Ctrl+Shift+V does not work
• Shift+Insert does not work
• Right click does not work
• Cannot type manually because keys like "n", "c", "Esc"

are intercepted as menu commands instead of text input

Expected Behavior

The input field should accept pasted text normally

What Should Happen?

Actual Behavior

Terminal intercepts keystrokes as menu commands,
making it impossible to complete authentication
