In Windows Photoshop cs5.
View->Show->Layer Edges
When you select a layer, it will now show the edges in blue. You can select multiple layers to see multiple paths.
Also slightly off topic, but if you want to click directly on the canvas, select an element similar to how Fireworks works. You can select the move tool and click “ Auto Select ” at the top of the screen. Change the drop-down list to " Layer " instead of " Group " if you want to select individual layers.
