Es más que un reemplazo del Bloc de Notas, es un editor de textos completísimo orientado a la programación.

Soporta múltiples ficheros al mismo tiempo y de tamaño ilimitado, “arrastrar y soltar”, edición hexadecimal, configuración de colores según la sintaxis para programadores (ya lleva HTML, Java, JavaScript, C/C++, VB por defecto), edición de columnas, ordenación, una barra de herramientas configurable, instalación en la bandeja de la barra de tareas.

Puedes conseguir el diccionario castellano para usar con UltraEdit en la Web del autor. La nueva versión mejora el soporte de FTP y de macros, y corrige algunos “bugs”.

Ofrece soporte de UNICODE, auto-completado de texto, mejoras en el resaltado de la sintaxis (con estilos de fuentes), soporte para guardar y extraer múltiples elementos del Portapapeles, auto-corrección de palabras clave, la posibilidad de borrar “bookmarks” y saltar al anterior, soporte integrado de IME, y mucho más.
