[...] It doesn't matter anyways, because it is part of the structure of the commands that move around sexprs. The first time I killed my X-Server I simply wanted to 'kill the s-expression before point'. I didn't read in the documentation that this command exists and that it is bound to `C-M-'; it's just the logical binding when you are familiar with `M-C-a', `M-C-f' etc. But I'd vote against binding `kill-whole-line' to `S-M-'. The penalty for clumsy fingers is way to high. I'd have to be carefule and assure that I set my fingers right in order to use this command -- which means that it would me more inconvenient and complicated than `C-a C-k C-k', so I won't use it. [C-S-, or still better: `C-S-k' is fine, IMO.] Oliver -- 10 Prairial an 211 de la Révolution Liberté, Egalité, Fraternité!
