You can treat written texts in the same way as a figure or image. This means that you can select and enlarge, shrink, rotate, lock, and copy each line individually. You can now also select multiple elements at the same time. To do so, just pull a selection frame over them. This way you can move, enlarge, or shrink multiple elements at the same time.
You can also choose to group the elements together and they will behave as one single element. It is always possible to ungroup your elements and create a new group with new elements whenever you like.
