Re: Pretty org-entities in org-mode buffers

["Daniel E. Doherty" <ddoherty03@gmail.com>]

Eric and Carsten,

This is a really swell feature, Mr. Cleaver.  Just a reminder to those 
who might be reading this list, enabling CDLateX and org-pretty-entities 
make typing greek characters *really* easy.  Backquote a (`a) is enough 
to give you alpha, `b beta, etc.

These two features work really nicely together.

Regards,

Down the rushy glen,

For fear of little men.
