[Sway] Clean install from Live Sway ISO: Win-d does not work any more

People,

I have been using Sway for a quite a while now via a KDE Live install but when I did a clean install recently from the new Live Sway ISO, generally everything went pretty well - except now the Win-d hot key does not allow me type a command at the top of screen. I presume there is a way to turn this on but it should be on by default?

Thanks,

Phil.
