> <\body> In this chapter, we discuss some of the general editing facilities that are implemented in . Of course, this includes basic operations that can also be found in other editors: \Pcut and paste\Q, \Psearch and replace\Q, etc. But, more interestingly, some of these facilities take advantage of the additional structure of documents. Typical examples of \Pstructured editing features\Q are \Pstructured cursor movement\Q and \Pstructured variants\Q. Traditional operations such as \Psearch and replace\Q also attempt to exploit the document structure. For instance, when searching in math mode, you will only find matches that are also in math mode. <\traverse> >
