The buffer is the basic editing unit; one buffer corresponds to one text
being edited. You normally have several buffers, but at any time you are

+editing only one, the current buffer, though several can be visible
when you are using multiple windows or frames (q.v.). Most buffers
are visiting (q.v.@:) some file. @xref{Buffers}.
Case conversion means changing text from upper case to lower case or
vice versa. @xref{Case}.

+Case folding means ignoring the differences between case variants of

@item Character
Characters form the contents of an Emacs buffer. Also, key sequences
(q.v.@:) are usually made up of characters (though they may include
other input events as well). @xref{User Input}.

+Character folding means ignoring differences between similarly looking
+characters, such as between @code{a}, and @code{@:a} and @code{@'a}.

Quoting means depriving a character of its usual special significance.
The most common kind of quoting in Emacs is with @kbd{C-q}. What
constitutes special significance depends on the context and on

inserts itself; so in this context, a special character is any character
that does not normally insert itself (such as @key{DEL}, for example),
and quoting it makes it insert itself as if it were not special. Not
