Change pocketed, I took bags (4)
I believe the answer is:
edit
'change' is the definition.
(edit can mean to change or alter)
'pocketed i took bags' is the wordplay.
'bags' says the answer is hidden in the clue.
'EDIT' is hidden in the letters of 'pocketed i took'.
(Other definitions for edit that I've seen before include "Emend" , "Change text" , "What our boss does" , "Amend and correct" , "Amend text" .)
