Select layer above or beneath current layer with a shortcut

[IVO237864061twd]

I want to use the shortcut ALT+[ or ALT+] to select the above or beneath layer but when i press it nothing happens.
My goal is to integrate it in an Action so i need tu use a shortcut instead of clicking with the mouse (that would select the layer by the name).
I tryed to change the shortcut but i didn't find anywhere in Photoshop shortcuts.
Aprecciate the help.

Are you using a US keyboard layout and or an English language version of Photoshop?

The following Relative Layer Keycuts should work – if you have a layer active and the next layer is visible:

Select/target front (top) layer = Option/Alt + .

Select/target next layer up = Option/Alt + ]
Select/target next layer down = Option/Alt + [
Select/target back (bottom) layer = Option/Alt + ,

Move current target layer to front (top) layer = Command/Control + Shift + ]
Move current target layer up = Command/Control + ]
Move current target layer down = Command/Control + [
Move current target layer to back (bottom) layer = Command/Control + Shift + [

You can download the previous as an action here and drag the steps into your action:

Portuguese version, the keyboard i'm not sure.. I've downloaded the action you sent. I think it will work just fine now. Thanks a lot for your help!

Layer invisibility can be worked around (otherwise a script would be needed):
