9 Faces ******* RefTeX uses faces when available to structure the selection and table of contents buffers. It does not create its own faces, but uses the ones defined in ‘font-lock.el’. Therefore, RefTeX will use faces only when ‘font-lock’ is loaded. This seems to be reasonable because people who like faces will very likely have it loaded. If you wish to turn off fontification or change the involved faces, see Options - Fontification.
