Ctrl +J in Photoshop is the shortcut for the “Jump to Layer” command. When you press Ctrl +J, Photoshop jumps to the layer that’s currently selected in the Layers panel.
This is a question that many people ask, but the answer is not as simple as it may seem. Ctrl + J in Photoshop is a keyboard shortcut that allows you to duplicate a layer. However, there are a few things you need to keep in mind when using this shortcut.
First, Ctrl + J will only work if you have a layer selected. If you do not have a layer selected, the shortcut will not do anything.
Second, the duplicate layer that is created will be placed directly above the layer that was duplicated. This can be changed by holding down the Shift key while pressing Ctrl + J. This will cause the new layer to be placed below the selected layer.
Finally, keep in mind that duplicating a layer does not duplicate the contents of that layer. If you want to duplicate the contents of a layer, you will need to use the Copy command (Ctrl + C) and then Paste command (Ctrl + V).
This is a great command to use when you need to quickly move to a specific layer in your image.
