You can use the Style Tree to select entities for editing. This is useful when the entity that you want to select is not visible in the graphics window. You can also right-click an entity to open a shortcut menu from which you can select commands relevant to the selected entity.

You can select more than one entity at a time using the CTRL or SHIFT keys. When you select more than one entity on the Style Tree and right-click, the shortcut menu that appears shows only the common and valid actions that you can perform on all the selected entities at the same time.
