Change rising tide (4)

I believe the answer is:

edit

'change' is the definition.
(editing is a kind of changing)

'rising tide' is the wordplay.
'rising' says the letters should be written in reverse (going up in a down clue).
'tide' back-to-front is 'EDIT'.

(Other definitions for edit that I've seen before include "Alter text" , "Prepare (material) for publication" , "This is an act of cleaning" , "What our boss does" , "Make changes to (text)" .)

I've seen this clue in The Mirror.
