Moving layers from one document to another

When I am talking about documents, I mean any image file that you open in the Editor.  In your case, you have many "objects"/documents that are open in separate tabs or windows in the Editor.

You turn off the tiling by selecting Window>Images>Consolidate All to Tabs.  This allows you to have a single document/object/window in view at a time.

So, although my prior example may look very different to your workflow, the principle is the same.  In the following example, I have 4 separate flower image documents open in the Editor.  In a couple of them I created a heart shape layer.  My screenshot shows that I have selected and dragged the heart, using the Move tool, from window #1 to window #2.  Instead, of selecting the layer in the window, you can select the layer from the Layers Panel to the window, as is demonstrated with window #3 and #4 (4 has the source layer).

One other option to tiling the windows is to float them.  This allows you to open and resize each window and place them wherever you want on the screen.  You can enable this feature in the Preferences>General tab (Ctrl+K):

And here is the dropdown menu in the Duplicate layer dialog that I mentioned:

Perhaps here is an easier way for you to copy and paste layers from one document to another. 

1. Open the two documents.
2. Tile the two documents by using the Window>Images>Tile command.
3. Select one or more layers in the source document.
4. Click and drag the layers to the target document. You can either drag the layers from the layers panel or directly from the image window.

I answered this in your other thread.  😉

Is there a way if I create a cluster of objects (layers) on one page to copy those and paste them into another document?

There are probably several methods to do that, but here is one that is fairly easy.

Below is a screenshot composite showing two untitled documents.  The first (Untitled 1)has a red background layer with 3 shape layers, a text layer and another blank layer.  The second (Untitled 2) has a plain green background layer. 

1. Select the layers that you want to copy.  They do not need to be contguous. I have selected the text layer and one of the shape layers in Untitled 1.
2. Right-click on one of the selected layers and choose Duplicate layers.  This brings up a Duplicate Layers dialog.  (You can also select Duplicate Layers from the Layers menu.)
3. All files open in the Editor will be listed in the dropdown menu of the dialog.  Select the one that you want to copy the layers into and click OK.  (If you only have one layer selected to duplicate, you can also rename the layer in the dialog.)
4. The selected layers will be pasted into your chosen open file - here Untitled 2.

I hope this helps.
