by the way - for anybody reading the archives:
I had to make a minor update to the code that Deniz provided:
(defun hello-there ()
(interactive)
(call-interactively 'move-end-of-line)
(unless (looking-back ";")
(insert ";"))
(newline-and-indent))
I updated line 3 above because I was getting the error "Wrong Number of
Arguments". A little googling led me to the solution.
Thanks again!
