Refer to everything due for revision (6)
I believe the answer is:
allude
'refer to' is the definition.
(I've seen this before)
'everything due for revision' is the wordplay.
'everything' becomes 'all' (all things).
'for revision' is an anagram indicator (I've seen this in other clues).
'due' is an anagram of 'ude'.
'all'+'ude'='ALLUDE'
(Other definitions for allude that I've seen before include "Refer briefly or indirectly in speaking" , "Make reference to in passing" , "Refer (to) in passing" , "Mention in passing" , "advert" .)
