Keyboard shortcut Shift+Up not working in team agent mode on Windows Terminal

Description:
When using team agent mode in Claude Code, the keyboard shortcut Shift+Up does not work for navigating between agents.

Environment:

• Claude Code version: 2.1.50
• OS: Windows 10
• Terminal: Windows Terminal

Steps to reproduce:

1. Start Claude Code with team agents
2. Try to navigate between agents using keyboard shortcuts

Expected behavior:
Both Shift+Up and Shift+Down should allow navigating through agents in both directions.

Actual behavior:

• Shift+Down: Works correctly, allows switching to next agent
• Shift+Up: Does not work, no response

Additional context:
This appears to be a Windows Terminal specific issue with the Shift+Up key combination not being properly captured.
