symbol.el is an Emacs lisp script which allows one to easily insert Greek, mathematical, and other Unicode symbols in Emacs.


  1. Load into Emacs via e.g. (load "~/emacs/symbol.el") in your .emacs file
  2. Type a character and use the backquote key to cycle through associated symbols:
  3. b <backquote> --> β <backquote> --> b
    (Ctrl-<backquote> will insert an actual backtick character)
  4. If you like, customize the key used for this by editing symbol.el.


The latest version of symbol.el can be found here: symbol.el.


The method of cycling through alternative characters was taken from the excellent TeXmacs program.
