I am not able to move object in play mode?

Hi, I am new to unreal engine. I am trying to make a magnet in an unreal engine. using this tutorial UE4 Magnets using Physics Constraints in Unreal Engine 4 Tutorial How To - YouTube. I am Stuck at testing when I made something as he shows and then I tried to move the magnet in play mode but It is complete not showing me any mouse cursor to move the magnet I tried shift+fn+f1 but not result. I am Having Lenovo ideapad320 I5ISK. In the editor, I am able to move Object.
