Gnome Shell by default uses the Super (Windows) key to display the activities overview. But I'd prefer to use the Super key to invoke Synapse. Right now I have to press Super+Super+Spacebar in order to invoke Synapse which is annoying (Super+Spacebar is the binding to invoke Synapse).
Is there any way to remove the default Gnome Shell mapping? In the keyboard shortcuts system settings, only the Alt+F1 binding appears for the activities overview action.
