In software like MicroSoft Office and LibreOffice, the user can CTRL+Drag to create a copy of the shape/collection, which moves with the mouse. When the user releases the mouse, the copy of the selection drops there.
On the other hand, if we create a copy the selection using CTRL+C and CTRL+V, then we have to click on the copy and move it to the new position. Thus the CTRL+Drag method is more efficient.
Would it be possible to introduce it to yEd?
