• Clicking the eye icon next to any layer on the Layers panel will hide/show the layer.
• Option + (Mac) | Alt + (Win) -clicking on the eye icon hides/shows all other layers
• Control -click (Mac) / Right Mouse -click (Win) the eye icon shows both of these options as menus.
However, if I need to toggle the visibility of multiple selected layers at once, then these shortcuts don’t do what I need them to. Instead, I tap “V” to select the Move tool, and then tap 00 (zero+zero) in quick succession in order to set the opacity of the multiple selected layers to 0 (zero). In order to “show”the layers again, I tap the 0 (zero) key once to set the opacity of the layers to 100%.
