Does not work at my side because a combo is expected: (Meta +...) neither @Heavymetalpenguin94 works because of the same reason (Ctrl + Meta + ...).
STRANGELY enough when installing a vanilla manjaro in a VM, the Launcher (of whatever it is called) opens at pressing on Super. No way i’m going to completely reinstall my system.
Edit: Nevermind, I got it working by assigign Alt+F1 according to this thread.
Still weird that this pesty regression pops up every time.
