  • receiving the hierarchical structure expressed in a first digital format, wherein the hierarchical structure includes a plurality of elements and defines hierarchical relationships between the elements, and wherein each element has a presentation property, and wherein a single one of the elements has focus;

    forming a tree model of the hierarchical structure comprising a plurality of levels ranked with respect to one another, a plurality of nodes, and at least one branch, wherein each node represents a single one of the elements, and wherein a single one of the nodes is a root node of the tree model and occupies a highest level, and wherein a given branch connects a first node in a first level to a second node in a level directly below the first level, and wherein each branch represents a hierarchical relationship between the nodes connected by the branch;

    using the tree model to produce an original script expressed in a second digital format, wherein the original script includes the presentation properties of the elements represented by nodes in;

    (i) the same level as an original focus node, and wherein the original focus node is the node representing the element having focus, and (ii) a selected number of levels higher than the level of the original focus node; and
