And since you apparently want to match characters which *are* letters rather than those which are *not*, `\s' is the appropriate construct with the `w' code: "^\\sw+:" Again, don't be afraid to use 0 as the font-lock-keywords SUBEXP and avoid `\(...\)' groupings when they're not necessary. > BTW, i'd have written: > > "^[-\\S]+:" > > but it doens't work eather. Can anybody explain me what I'm missing? Inside of the `[...]' construct, backslash constructs are not special (RTFM). But in Emacs 22 you can do this: "^[[:alnum:]]+:" -- Kevin
