Select or de-select multiple layers in ArcGIS Online at once

Idea created by dabush2 on Dec 5, 2014
    I created a map in ArcGIS Online that has 10 layers. I would like to be able to select or de-select all of the layers at once, rather than clicking on each layer to turn them all on or off.

    Kind of like select 1 layer, hold the shift key, select the last layer, and all layers would be selected.
