Could you maybe tell us what was your output? Are you sure you really did C-M-% and not M-% ? What other line did it work with? By the way, should there be no other occurances of 'n', this would also be nice for a macro... Greetings Malte ^ permalink raw reply [flat|nested] 6+ messages in thread

GNU Emacs 21.4.1 (i386-redhat-linux-gnu, X toolkit, Xaw3d scroll bars) of 2006-03-07 on hs20-bc1-6.build.redhat.com so I did M-x query-replace-regex I am still don't know why it did not fire. ^ permalink raw reply [flat|nested] 6+ messages in thread

Okay, that is very helpful to find the problem. It would be useful if you left out part of the search string to see if Emacs fails to find that or the other part. Try e. g.: C-M-% ^ *\(//\)<RET>whatever<RET> or C-M-% \(.*'n',\)<RET>foobar<RET> >>Are you sure you really >> did C-M-% and not M-% ?
