Does a rotate tool let you turn only text around?
DTP programs let you work with graphics: you can draw shapes, fill them with text or colour, insert graphics or special characters from the program, or import them from another program, and you can move them all easily around the page.
There are many things you can do with text and graphics: you can use an align command to put them in a straight line, horizontally or vertically, and a rotate tool lets you turn them around. You can bring text to the front of a shape or graphic or send it to the back so that you can’t see it. You can also wrap text around a picture or inside a shape.
