本文详细介绍了Emacs中的搜索和替换功能，包括如何使用快捷键C-s进行交互式搜索，如何通过M-%和M-M-%进行文本替换，以及如何在缓冲区中循环搜索历史记录和执行替换操作。

Key	Meaning
C-s	Search
M-%	Replace
C-M-%	Replace Regexp

C-s tells Emacs to start an interactive search. Type a search term at the prompt, and Emacs will move the cursor to the first occurrence. Press C-s again to find additional occurrences.

While at the I-search: prompt, C-s will restart the last search, M-p cycles through previous searches, and M-y yanks (pastes).

To replace text, press M-% (M-S-5). Emacs can also do replacement of regular expressions (C-M-%).

At the prompt, type the string that should be replaced at the prompt, hit enter, type what it will be replaced with, and hit enter again to start the replacement. y replaces the current match, n skips it, and !replaces all further matches in the buffer. Just like M-x, the up arrow key at the replace prompts cycles through previous entries.

Note: search and replace are case sensitive by default.

After performing a search or replace, C-u C-SPC will jump back to the point in the buffer where it began. This is an example of using prefix arguments, which are explained later.
