Programming in Emacs Lisp

5. A Few More Complex Functions

In this chapter, we build on what we have learned in previous chapters by looking at more complex functions. The copy-to-buffer function illustrates use of two save-excursion expressions in one definition, while the insert-buffer function illustrates use of an asterisk in an interactive expression, use of or, and the important distinction between a name and the object to which the name refers.

5.1 The Definition of copy-to-buffer		With set-buffer, get-buffer-create.
5.2 The Definition of insert-buffer		Read-only, and with or.
5.3 Complete Definition of beginning-of-buffer		Shows goto-char,

                                point-min, and push-mark.
