I’ll often get PSDs from my visual designers with hundreds of layers. When I’m slicing it up, I’ll need to find a specific layer. And much of the time, I don’t instantly understand the layer architecture that was defined.

Using the “Auto Select layer” option on the move tool gets partway there, but it chokes on layer groups.

The quickest route possible: Alt-right-click That will immediately select the layer of whatever you clicked on. (The move tool (V) must be active. This doesnt work while on other tools.)

(On Mac, this has an additional click: option-click. then the revealed menu has your layer currently selected. click it.)
