Copy an element into a different tab

Option 1

Press on the desired element and drag it into the tab (or within the tree). There will be a mirror option and a clone option. 

Option 2

Another way to mirror or clone elements is to 1) select the element, 2) press Shift+C to copy, and 3) press Shift+V to paste

This dialog will show up and you can select Mirror or Clone:
