   Prettify Symbols mode is a buffer-local minor mode that replaces
 certain strings with more attractive versions for display purposes.
 For example, in Emacs Lisp mode, it replaces the string @samp{lambda}

-non-programming modes as well.  You can customize the mode by adding
-more entries to @code{prettify-symbols-alist}.  More elaborate

address@hidden is not appropriate.  There
