Review on Logitech K380 Multi-Device Wireless Keyboard white, english by Mateusz Sowa ᠌

Personally, I think it makes more sense to have F5 as the default key and not as a window management button. Those. If I need to refresh a browser window, I simply want to press F5, not F5 and Fn. However, you can also press Fn to view all open windows. Although you have to download software to achieve this, it's excellent that you can still change these keys' behavior back to their default setting. With my prior keyboard, I did not have this option.
