Duplicate and Move and Duplicate
Duplicate
This button is activated if any objects are selected.

If only one object is duplicated, move the mouse pointer to a marked point of the object and drag this point to the desired position. If more than one object is duplicated, move the mouse pointer inside a marking rectangle and drag this rectangle to the desired place.
