No, use the dependencies table (USER_DEPENDENCIES (?)) to find what table names are accessed. Then search for those names. Or grep those names to find the line numbers in the code and go straight to those line numbers. Or use (e.g.) perl to add a tag to each keyword, and search for the tag (which is easier than searching for each keyword).
:: DOS BAT FILE, invoke perl for each keyword (line wrapped for msg) for %i in (list the table names here) do perl -i.%i.bak -pe "s/(%i)/ /*!*/ $1/gi" source-file.pls
In this example I would search for /*!*/.
