Revise some selected items (4)
I believe the answer is:
edit
'revise' is the definition.
(thesaurus)
'some selected items' is the wordplay.
'some' indicates a hidden word (some of the parts of the word are used).
'EDIT' is hidden in the letters of 'selected items'.
(Other definitions for edit that I've seen before include "Revise text" , "Amend a publication" , "Rework (text)" , "Check text for publication" , "work on newspaper?" .)
