By default in 3ds Max you can hide with shortcut: main toolbar, command panel, ribbon, but other things like status bar, menu bar, layer toolbar, snaps toolbar and other you cant hide or show easy. So i create simply script with 7 buttons for hiding all parts of interface. You can just put this buttons on quick access bar. Hope it will be helpful for somebody.
Thanks Pete Addington(Lonerobot) for idea with keyboard pressed buttons
