Keep on editing paper? Not I (9)
I believe the answer is:
reappoint
'keep on' is the definition.
'editing paper? not i' is the wordplay.
'editing' indicates an anagram.
'paper'+'not'+'i'='papernoti'
'papernoti' with letters rearranged gives 'REAPPOINT'.
(Other definitions for reappoint that I've seen before include "put back in the post" , "put back in place" , "return post" , "Once again choose" , "return to job" .)
