6.10.1.1   Adding a Node in the Tree

Nodes may be added to the selection tree on the current level in two ways.

They may be added as a sibling to another selection tree element. Select an element as insertion point on the level in which the new node is to be inserted, and choose Add child > Node. The new node will be inserted as a sibling to the element selected as insertion point, either immediately after it if the element is a node or modifier or immediately after all conditions if the element is a condition.

They may also be added as a sub-node to another node. To add a sub-node, select the node that is to be the parent node, and choose Add child > Node. The new node will be inserted as a child to the selected parent node, after all conditions but before any modifiers.
