Rotation

All shapes can be rotated. There are two tools to do this: the Rotation slider, and the Rotation button. The Rotation slider can set the rotation angle to anything between 360 and -360 degrees. The Rotation button simply rotates the shape 90 degrees clockwise.

It a text shape with a 'tail' is rotated, the main body of the shape is rotated, but the position of the tail does not change, as shown below.

Reflection

The Reflection button is circled in the first screenshot below. Reflection works with lines, polygons and arrows, but not with text shapes, such as speech balloons. To reflect a shape, click on it, to select it, and then on the Reflection button.
