How do make Windows key (Super_L) to NOT bring up Search menu?

I would prefer to use Windows key as Super_L in emacs and possibly other apps. However, the key is programmed to bring up Ubuntu Search Apps menu. Is there any way to disable this shortcut, in other words un-map the Windows key from Search Menu?


To disable the binding of Super for bringing up the activities overview, issue following command in the terminal:

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

You can undo this with the command

gsettings reset org.gnome.mutter overlay-key

I was able to un-map the key using CompizConfig Settings Manager, via Ubuntu Unity Plugin sub-menu. I had to disable "Key to show the Dash, Launcher and Help Overlay" (see picture)enter image description here
