Unusual actions with the keyboard.
You're experiencing inconsistent arrow key behavior across different applications. It seems the issue varies depending on the software you're using—working normally in some but not others. The cursor also moves unexpectedly in tools like Snip & Sketch and the Windows search bar. You've already tried resetting your keyboard and mouse, unplugging them while using Snip & Sketch, but the problem persists. Since you don't have any USB devices or Bluetooth devices connected, it's unclear what external factor might be causing this.
