Stedi has a number of advanced features which make it one of the more powerful editors in existence today. A rich number of options exist for creating one's own personal environment while using the editor. These are stored if desired in a file which can be read at startup to recreate the environment each time the editor is used. Stedi also contains a very flexible buffer system with up to ten different buffers available for editing purposes, and a number of commands which are not normally found in other editors but which can be invaluable to programmers. In addition, there are ten `learn buffers' which can remember up to 100 key strokes each for replaying, and the keyboard can be completely reconfigured so that a key can perform multiple actions if desired. Macro's can be created as text files and executed either from memory or from file. The `folds' feature allows the user to organize his file according to segments which can selectively be displayed or hidden for editing purposes. The language for its regular expressions that can be used to define search patterns is very extensive.
