Disable CMD/Windows Key in Kali From Opening Activities Overview

I cmd+tab between apps all the time. With the release of Kali 2, it has this very annoying "feature" of zooming out all my app windows when I hit the cmd key.

Turns out the fix is very simple:

gsettings set org.gnome.mutter overlay-key ''

Once you run that in a terminal, magically the cmd key stops bringing up the windows.

yay for simple solutions.
