K. Searching and Replacement

Like other editors, Emacs has commands for searching for occurrences of a string. The principal search command is unusual in that it is incremental; it begins to search before you have finished typing the search string. There are also nonincremental search commands more like those of other editors.

Besides the usual replace-string command that finds all occurrences of one string and replaces them with another, Emacs has a more flexible replacement command called query-replace, which asks interactively which occurrences to replace.

K.6 Searching and Case		To ignore case while searching, or not.
