22 Chapter 2 • Working With Editors
File Operations
Editing within Emacs is done through a series of buffers. Each buffer may be edited separately
and the changes saved back to the disk. Files may also be opened into new or existing
buffers as shown in Table 2-4.

Search and Replace
There are two search and replace functions within Emacs. The first one simply does a simple
search (case insensitive by default) for the character string provided by the user. The second,
more complex search function does a search and replace on regular expressions. See Table 2-5
for a list of these commands.
