You have to evaluate it somehow. If you are reading your mail in emacs, just place the cursor after the closing paren and press C-x C-e. If not, just go to emacs and "C-h i elisp RET i edebug RET" or equivalently, type ESC ESC : (info "(elisp) Edebug") RET. Underlying assumption: you have the Emacs Lisp info files installed. > Anyway...
