What's Wrong?

When using Claude Code as an extension inside Cursor IDE (VSCode fork), the Command + Delete keyboard shortcut does not delete the entire line as expected. This keyboard shortcut is working in the standard terminal but not in the VSCode/Cursor extension environment.

What Should Happen?

The Command + Delete keyboard shortcut should delete the entire line of text at the cursor position, similar to how it works in most macOS text editors and in the standard terminal version of Claude Code.

Additional Information

This issue is specifically related to the Claude Code extension when running in Cursor IDE. The same keyboard shortcut works as expected in the standard terminal version of Claude Code, suggesting this is an IDE-specific integration issue. The extension may not be properly intercepting or handling the Command + Delete keyboard shortcut.
