No, because `add-hook' is called with non-nil LOCAL arg. > Shouldn't this hook do that only for *Backtrace*? We can sandwich add-hook inside: (when (eq (current-buffer) (get-buffer "*Backtrace*")) (add-hook ... ) Then would be less general: just protect *Backtrace* for accidental killing. So far that was my request so i'm fine with that.
