fragment <-previous: condition=[code] -> fragment

fragment <-next: condition=[code] -> fragment

Return the next/previous fragment of the double linked fragment list for which code succeeds. If code is omitted, these methods return the next/previous fragment of the list. While executing the condition, @arg1 is bound the candidate fragment. Execution may not alter the fragment list of the associated fragment<-text_buffer.

If no fragment can be found in the indicated direction, these methods fail.
