Graphics in the Gallery are grouped by themes, such as Bullets, Rulers, and 3D Effects. The box on the left of the gallery window lists the available themes. Click on a theme to see its graphics displayed in the Gallery window.

The default themes are locked; no items can be added or deleted from these themes. The locked themes are easily recognizable by right-clicking on them; the only available option in the pop-up menu is Properties.

In a default installation, only the My themes theme is customizable, although new themes can be added as explained in Adding a new theme to the Gallery.
