I have Logitech K330 unifying keyboard with Fn key on it. I use it on MacBook Pro 2015 with macOS Mojave. For some reason when I press Fn key it does not do anything. I definitely need this Fn key behavior for terminal command line navigation (Fn+Shift+Arrow keys). I tried with Logitech unifying software too, it did not work. Has anyone faced a similar situation?
