Copy to the clipboard supports Text or image. There are also two types of copy using Photoshop Copy Ctrl+C and Copy Merge Shift+Ctrl+C when the first one is used it should copy transparent and filled pixels from a layer. When the second one is used a composite of the selected area is copied to the clipboard. Here I used CC 2015 to try to show the differences. the top two layer were created using the two different Copy the Ctrl+v paste I then turned off background visibility
