Het, this is a known bug that started in Cursor 3.0.x. A few keybinding editor commands like next or previous editor, split editor, move editor to group trigger in keyboard troubleshooting, but the command has no effect in the UI. It’s being discussed here: Keyboard shortcut does not work since upgrading to 3.0.13
Most of the issues were fixed in 3.1.15. A few users in that thread confirmed it. Update Cursor via Help > Check for Updates or download it from the website, then test again.
If it still happens after updating to 3.1.15 or newer, post in that thread with:
- the exact version string from Help > About > Copy
- which shortcut and which command it’s mapped to like
nextEditor,nextEditorInGroup, etc. - whether you use Editor Layout or Agent Layout
