Question about Logitech MX Keys S

The F-keys can be permanently activated as standard function keys so that you can only press the F-keys without holding the Fn key. To do this, press the key combination Fn + Esc to switch between multimedia and F-key modes. In F-key mode, the F1 to F12 keys function as normal function keys.

Alternatively, you can also customise this setting using the Logitech Options+ software if you want to make further individual assignments.
