In WAB it is possible to turn all layers on/off at the same time using Ctrl + click on the visibility box of any layer. Alt + a does the same in Map Viewer. But neither of those works in ExB. Any other way to do it or it is not possible in ExB?
Ctrl + click the visibility box works in Map Viewer Classic based WAB, Map Viewer Classic and Scene Viewer but neither in Map Viewer, ExB nor Scene Viewer based WAB...
