There is a Magnify icon in the PCB Library view that when clicked, I can figure out what it does and how to turn it off. Once its clicked I get a tiny magnifying glass on my cursor that I don't know what to do with and its function is not obvious. Once enabled, its even harder to figure out how to turn it off. I don't know what I did to turn it off but eventually it went back to normal. What's this for
