Logitech K780 Keyboard CMD & Start keys switched

Hi, I found yesterday that my Logitech K780 wireless keyboard CMD and Start keys had switched function which I found particularly annoying when using cut/paste functions.

After trying head-scratching, system settings, unpairing/repairing etc I eventually found that there is a key combination which either sets this keyboard up for Mac or Windows and I must have accidentally pressed the 'Windows' combination earlier in the day.

The way to switch the keys back to the Mac configuration is to hold down fn+o for 3 seconds.

(Switching to the Windows config requires fn+p for 3 secs)

hope this helps someone
