Re: Prettify keywords

[pietru]

Currently I can use the following code, which will take care of
"\alpha" and "\alpha\beta".  But not "\alpha-\beta" or 
"\alpha+\beta" which are completely appropriate in mathematical
expressions.  Can this be achieved such that  "\alpha-\beta"
gives α-β.

(defun pretty ()
  (push '("\\alpha" . ?α) prettify-symbols-alist)
  (push '("\\beta" . ?β) prettify-symbols-alist)
  (prettify-symbols-mode))
