Just edited my reel (6)
I believe the answer is:
merely
'just' is the definition.
(I know that just can be written as merely)
'edited my reel' is the wordplay.
'edited' is an anagram indicator.
'my'+'reel'='myreel'
'myreel' is an anagram of 'MERELY'.
(Other definitions for merely that I've seen before include "Just one" , "'Only, and nothing more (6)'" , "Simply - only" .)
