GNU Emacs is a text editor designed for POSIX operating systems. It is often considered complex since it was developed long before modern computer conventions and terminology existed.
However, GNU Emacs offers efficient commands for common but complex actions, plus plugins and configuration hacks developed around it over 40 years. Once you learn...
