You can change the style of a shape or image by selecting it and pressing the Information button, located in the toolbar. A popover window will appear, showing relevant style choices for the selected shape or image. If none of the six options are appropriate, you can choose specific styles for the object by pressing the Style Options button. Doing this will show an additional window. If the selected object is a shape, the window will show Fill and Border tabs, letting you change both the border style and fill style of the shape. If the selected object is an image, the window will show just a Border tab, letting you change only the border style of the image.
When you press the Information button, alongside the Style tab, for a shape, there are also two other tabs, a Text tab and an Arrange tab. For an image, there is no Text tab. The Text tab lets you specify font face, size, color, text styling and alignment for any text that has been added to the shape. The Arrange tab lets you choose a Z-order for the shape, that is, whether the shape is on top of all other objects in the slide or whether it is underneath all other objects in the slide or whether it is somewhere inbetween.
