View on Netflix blocked?

Hello. I don't know exactly how to describe it, but when I was in the Netflix menu and wanted to scroll down with the mouse, it didn't scroll down but enlarged or reduced everything. I switched off my laptop and the mouse went back to normal, but the view is still small or a column. How do I get this undone?

Hold down the CTRL key and then slowly scroll up and down with the mouse. Then you will see that this way you can zoom in and out
