@ symbol triggering project selection menu instead of typing - how to fix?

When I try to type the @ symbol in Cursor, it triggers a project selection menu instead of typing the character. I’ve checked keyboard shortcuts and can’t find any binding for @ that would cause this. The “Go to Symbol in Workspace” command is correctly bound to Cmd+T/Ctrl+T. I’ve reviewed my settings.json and don’t see anything obviously related to this behavior.

I’ve already tried:

  1. Searching for @ in keyboard shortcuts
  2. Checking for extension interference
  3. Looking for Cursor-specific settings

Has anyone else encountered this issue or know how to resolve it? Any suggestions for further troubleshooting would be appreciated.

This can be closed. The Notes extension has been responsible for this behavior.
