i see the icon fn on the top right corner on the screen and I tried to remove it from the screen but It didn't work. What do I do now?

If you click on that icon, you will likely get a dropdown menu, or something else happens. You can also try a right-click on that "fn" icon. What happens when you try that?

What would you like to do now?
Show a screenshot, please!
