How can I quickly multiply 1 pair of elements to 200 pairs? Now I have to do a lot of copying by constantly clicking the mouse, select the item to copy, then I click the mouse again, then I aim at the insertion point again, then I click the right mouse button again, I aim, I choose to copy ... Can this be done as fast as in my old P-CAD program with drag and auto paste? (In this web  IDE  not  support  ctr+drag with paste and not support drag +paste, i can not  a finded) Thank's
