12.3.2 Control characters

\c is used to denote a control character; the character following \c is the name of the control character. For instance, /\cM/ matches the character control-M (a carriage return, code point 13). The case of the character following \c doesn't matter: \cM and \cm match the same character.

Mnemonic: control character.
