Emacs es un poderoso editor utilizado tanto por desarolladores de Java, C#, Ruby o PHP como por escritores, científicos y editores. Revise esta entrada para conocer más sobre emacs.

Hay que hacer notar que C-x significa Control-X mientras M-x significa Meta-X donde "meta" se refiere a la tecla Alt ubicada en el lado izquierdo del teclado. La tecla Space se refiere a la barra espaciadora.

Cuando se da una palabra en lugar de combinación quiere decir que hay que pulsar M-x antes.

Estas combinaciones estan extraídas del libro Unix in a Nutshell. La primera columna muestra la combinación de teclas, la segunda el nombre de la función en inglés y la tercera da una breve descripción. Consulte el original en inglés aqui.
