Kde use super key to show desktop

Question

How can I assign the super key ( windows key ) to the show desktop action in Plasma 5.8

By default it shows the application launcher.

Answer 1

So far ksuperkey looks the only solution. The documentation says it is not necessary for plasma 5.8 but actually make the trick.

By default I have Control + F12 assigned to show desktop action so I just need to:

• Remove the association ALT F1 in the application launcher widget ( other wise super will also open this )
• run in a terminal ksuperkey -e 'Super_L=Control_L|F12'

If it works you can add this to the startup application

Answer 2

Here is a newer answer, which might make that a duplicate of the above (although I'm not really sure: this question has no accepted answer, while I'm about to mark the answer under the other question as definitive).
