What's Wrong?

When the user goes into the /plugin menu to add a new marketplace, the text area that accepts the marketplace string closes automatically when you hit the 'n' key. No other letter does this. I've tried this in a few different environments and get the same behavior.

What Should Happen?

The add marketplace dialogue should let you type a string with the letter 'n'

Error Messages/Logs

No error, it just goes back to the previous menu.

Steps to Reproduce

1. Open 'claude'
2. Type '/plugin'
3. Tab twice over to Marketplaces
4. Hit <enter> on Add Marketplace
5. Type 'n'
