Hey, this is a known issue. After certain interactions (like the built-in browser or the AI chat), focus can get “stuck”, and some keys stop working. That’s why Ctrl+X and Ctrl+V still work, but Backspace, Ctrl+Z, and the arrow keys don’t.
When the keys stop working, try:
Press Escape or Ctrl+1. This should move focus back to the editor.
If that doesn’t help: Ctrl+Shift+P > Developer: Reload Window
Also, please check one thing. When you can reproduce the bug, open DevTools and look in the logs for this message: "Skipping keybinding dispatch because browserViewFocused is true". If it’s there, it confirms the root cause.
The team is aware of this bug. Your report helps us prioritize it.
The keyboard input issue (backspace/Ctrl not working) has been addressed in a recent Cursor update. Updating to the latest version should resolve this.
