One can toggle docker visibility with shift-tab shortcut. One can toggle dockers and toolbars visibility with the tab shortcut. The problem is if you toggle with the second one, it will toggle both visibility so if your dockers were hidden, it will display them again. But what if you only wanted to toggle the toolbar visibility? Should one be forced to toggle back dockers again? I think it's best to either make a 3rd shortcut which only toggles the toolbar or just to make them independent from each other.
Sorry but it's the other way around :) toggle dockers will force showing toolbars again when it should only display dockers right ?
If the toolbar has been hidden by use of the Tab key, toggling dockers on will bring the toolbar back. Then toggling dockers off does not remove the toolbar. I think this is a bug and the docker toggling should not affect the toolbar.
