El acceso del usuario común (CUA) es un estándar de interfaces de usuario para los sistemas operativos y programas informáticos.Fue desarrollado por IBM y publicado por primera vez en 1987 como parte de su arquitectura de la aplicación de sistemas. El CUA contiene normas para el funcionamiento de elementos tales como cuadros de diálogo , menús y atajos de teclado que han llegado a ser tan influyente que son implementadas hoy en día por muchos programadores que nunca han leído la CUA.
