7. Build, Edit and update a Tree

Building a tree is often a process of frequent revision. Also, new tree projects can often make use of subtrees from existing models.

This chapter reviews the basic tree building commands and covers a set of features designed to help you move, remove, and duplicate parts of a tree. Smaller parts of the tree are called “subtrees”.

In this section we cover the following topics too:

• Annotating the Tree

• Controlling Layout, Formatting and Display of Trees
