Shortcut to open selected image?

[laurent45654]

I'm sure I'm missing something but how can I customize the shortcut to open the selected image?

I'm on macOs and when I press Enter, it opens the image but in full screen mode, however I want to open the image in "normal" mode, just like when I double-click on it.

So I guess I'm wondering what command is the equivalent of double-clicking an image?
