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:
