The “priority” buttons are very useful, especially when your slide contains many objects or layers. By priority, we mean these buttons will allow you to change the “order” of how your objects appear in relation to each other. You can move objects behind, or in front of, other objects.
This ordering is controlled by a set of four buttons. They are quite simply, “Bring to Front”, Send to Back”, Bring Forward” and Send Backward.” Although they appear as a sub-menu to the “Drawing” menu, it’s much more convenient to have them displayed on the toolbar for easy access.
The “Group/Ungroup” set of buttons are also very handy to have on the toolbar. These buttons allow you to quickly group or ungroup a selection of objects for moving, copying, or editing. The grouping feature helps to keep your slide “organized” for easy editing. Keep in mind, that any animation effects applied to a “group” will be lost when “ungrouped”, and any effects applied to individual objects before grouping will be lost when they are grouped. So it’s a good idea to make a duplicate of the slide before editing, just in case.
