Please consider specifically the documentation of the function font-lock-add-keywords that I used in the example. Its documentation points to that of font-lock-keywords, which contains the description: FACENAME is an expression whose value is the face name to use. Instead of a face, FACENAME can evaluate to a property list of the form (face FACE PROP1 VAL1 PROP2 VAL2 ...) in which case all the listed text-properties will be set rather than just FACE. This currently states that a face name is expected. Since the Elisp documentation also states: "Unless otherwise stated, we will use the term =E2=80=9Cface=E2=80=9D to refer only to named faces.", th= e notion of "face" in the description above also does not include anonymous faces. Would it work to mention that "face FACE" can also be omitted, i.e., that an anonymous face can also be specified here? Thank you and all the best, Markus
