Try also binding [delete] and "\C-d" (likewise, the ASCII character to which delete is translated). I wonder if an alternative implementaton would work: instead of binding any keys at all, make backward-delete-char-untabify-method buffer local and toggle its value between `hungry' and the global value. -- Kevin Rodgers Denver, Colorado, USA
