"\"")) Also, the numeric character values are already present in `font-lock-defaults'. Regarding the "generic string delimiter" syntax class: While checking the above with XEmacs 21.5 I saw that stuff like "\verb{foo}" will get fontified correctly even with a normal string delimiter (syntax class 7). I don't know if this is correct, but at least it is different from XEmacs 21.4. -- Ralf
