 Search/replace with regular expressions
 Filtering block contents through an external program
 Linear multilevel undo/redo

 Hexadecimal editing mode
 Editing of mmap'd files or devices in replace mode
 Frame drawing mode (first seen in Lexicon)
 File selection box (inspired by Turbo C)
 Built-in postfix calculator. It uses ncurses for display, mouse and part of the keyboard handling. The application has a built-in table of key assignments for xterm, rxvt and some less familiar terminal types. History
According to the HISTORY file in its sources, Alexander V. Lukyanov started writing it in 1993 while using a BESTA machine. Over the next four years, he rewrote it into C++, and published it in 1997 under the GNU General Public License. References
