how to hide whole desktop menus

[Jerry Geis <geisj pagestation com>]

Is there a way to have a script that would use 

dbus-send and send an event that will HIDE the entire menu structure???

I am using CentOS 7.1 gnome 3.8

I found something that sends 'Main.overview._dash.actor.hide()' and tried

to find something that would hide() the main menu but have not found it.

Is there a way to do this? I dont want any menus to show.

Thanks
