What's Wrong?

In the Claude desktop app on Windows (Code tab), Ctrl+V does not paste anything in the built-in terminal panel. This happens both in a local PowerShell tab and inside an interactive ssh session. Ctrl+Shift+V does paste.

Reproduced on two machines with the same app build:

• Windows 11 Pro 10.0.26300, Claude desktop (MSIX) 2.19675.0.0, Claude Code 2.1.286
• Windows 10 IoT Enterprise LTSC 10.0.19044, Claude desktop (MSIX) 2.19675.0.0

What Should Happen?

Ctrl+V pastes the clipboard text into the terminal, as in Windows Terminal and the VS Code integrated terminal on Windows.

2. Open the terminal panel in the Claude desktop app (local PowerShell 7.6.6).
3. Press Ctrl+V: nothing is pasted.
4. Run ssh <host> and press Ctrl+V again: nothing is pasted.
5. Press Ctrl+Shift+V: the text is pasted in both cases.
