Substituting left super key for shell overlay.
I have a professional keyboard but it is gaming focused. It has no left super key and it is frustrating to bring up the shell overlay, because I have to go to the top right corner with my mouse. I looked around in the keyboard settings but that key doesn't seem to be in there. So I can't figure out how to change it. I am hoping there is some kind of magic I can do in the shell to change this.
I want to substitute the key with the a combo of the left-alt, left-shift, and Z. If that is not possible the right super key is fine. I might be using the wrong keyboard layout.
I am running Gnome 3.14 on Fedora 21.
