Cannot turn WiFi on with the sidebar

[#1]

I am stupid !  I used to have a network sidebar in Windows 10 where I could turn on and off WiFi among oher things.  I have forgotten how I get the sidebar to show !  I am sure I pressed the Windows Key plus a letter or something like that.  Anyone know ?

Thanks.

Windows key + A or click the message icon on far RHS of taskbar.

Yes, that is exactly it - Windows key + A !  Thank you so much.  I could kick myself for forgetting - too much lockdown !

I wonder why "A" ?  Well, I will not forget again.

A = Action centre.
