The “Windows key + d” (aka “Super + d”) minimizes all windows, i.e. it shows you the desktop. It works under Windows, it works under Ubuntu, but for some mysterious reason, under Manjaro (XFCE), it’s “Ctrl + Alt + d” that I’ll never get used to.
How to use the well-known “Super + d” shortcut?

You can find my

Hyper + g gedit Hyper + k konsole Hyper + f file browser (thunar)
And if Hyper Hyper, then Scooter, of course:
