And you might want to add a check for (eq major-mode 'lisp-mode), or make after-change-functions a local hook variable in Lisp mode buffers (by putting the add-hook in a lisp-mode-hook function, and specifying the optional LOCAL arg). You might also have better luck if you call indent-region with a region that starts at the beginning of the line: (save-excursion (goto-char start) (line-beginning-position)) -- Kevin Rodgers
