So you really couldn't figure out what "Super key" meant, even with context? I feel like you are being hyperbolic. This isn't magical hidden Linux knowledge. Honestly, if not being able to find what applications you have running, and not even trying pressing the large button on your keyboard with the windows logo on it was so traumatizing, you might want to just avoid Linux entirely.
No, I didn't realize that the "Super key" was the Windows key, and no, I didn't think to try it. I never use the Windows key myself, because it's never needed. I'm either in a DOS or PS box, or if I'm working at the desktop, the taskbar gives me all the affordances I need including a 'Type here to search' box.

The KDE and GNOME developers have a direct usability goal. With respect to Slashdot's opinions, the Linux desktop would still be stuck in the 90s if we listened to them. Your perspective as a DOS/PowerShell user is not any more valuable, considering you barely use Windows as-is.
