When a defining symbol definer has an associated form parser, this parser function is used by the source location commands such as Expression > Find Source in the LispWorks IDE. Having identified the file where the definition was recorded, LispWorks parses the top level forms in the file looking for the one which matches the definition spec. When found, this match is displayed.
