Indicated editor not entirely keen (9)
I believe the answer is:
dedicated
'indicated' is the definition.
The definition and answer can be both to do with communicating as well as being past participle verbs.
Maybe there's an association between them I don't understand?
'editor not entirely keen' is the wordplay.
I cannot really see how this works, but
'editor' could be 'ed' (abbreviation) and 'ed' is found within the answer.
This explanation may well be incorrect...
Can you help me to learn more?
(Other definitions for dedicated that I've seen before include "Customised" , "Hard working" , "Committed" , "Devoted to a task or purpose" , "Consecrated - single-minded" .)
