I should add some information to this to explain why I need some help: 1. "m-x describe-key" tells me that my "backspace" or DEL is bound to (backward-delete-char-untabify ARG &optional KILLP) =20 with value untabify. But if type lots of spaces (e.g. in the scratch or m= y .emacs) and then press backspace, it only goes back one character at a ti= me... not untabbing. 2. describe on my control-backspace reveals that this is bound to C-backspa= ce. But when I try to create any form of binding for C-backspace in my .ema= cs I get an error that control must be followed by a single character... so= I don't have a clue how to rebind this. Help greatly appreciated :-)
