Why can't you use the same technique to put a control character into the replacement string as Neon suggests for the search string/regexp (namely, C-q)? I'll admit, I don't understand why that solution works: it appears to replace the matched sequence of LFD characters with itself, instead of replacing it with just a single LFD character (or nothing at all, depending on the desired result). > Could this be related to the fact that > C- is no longer bound to 'set-mark'? It used to be, but now > C-h k reports nothing, (in fact, doesn't react at all) to that keypress. No. When you type C-SPC, your terminal is no longer sending anything for Emacs to interpret. Try C-@ instead. -- Kevin Rodgers
