LE is a text editor which appears something like the Norton Editor, but has many additional features:

• Rectangle select/copy/paste (block type is switchable)
• Search/replace with regular expressions
• Filtering block contents through an external program
• Linear multilevel undo/redo
• Customizable menus
• Color syntax highlighting (using regular expressions in an external file)
• Handles UTF-8 characters, based on locale settings
• Customizable keymaps for different terminal types (associating either literal strings or terminfo capability names)
• 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.
