Am I > missing something? Sounds like an Emacs bug to me "\\s " is working (in fundamental-mode). Anyway newline isn't whitespace in "most" modes. In quite a lot of languages a newline ends a comment. To make your regexp reliable i would use something like "abcd\\(\\s \\|$\\)" (note that this will match "abcd" at the end of the buffer too w/o a final newline). BTW: M-: (syntax-after (point)) RET may be useful. David
