Map 'Super' key to 'Alt+F1' (application launcher in many DEs)
ksuperkey allows you to open the application launcher in various DEs (such as KDE Plasma or XFCE) using the Super key (also known as "Meta" or "the Windows key"). If you hold down the Super key it will still act as a modifier key, allowing you to use it for other keyboard shortcuts. ksuperkey is a small desktop-agnostic application that runs in the background as a daemon. It was forked from xcape by Albin Olsson: https://github.com/alols/xcape
