how do i copy (and paste)
Select a Rectangle with your mouse (Click and Drag) or via your Touch Screen
Then press CTRL+C and CTRL+V (on mobile you can use the onscreen Buttons at the bottom of the screen)
If you run out of CTRL keys you cannot copy/paste anymore (that's the gimmick of the game :P)
i figured it out before you replied, but you helped newbies.
CTRL + C CTRL + V
