Controlled strike at parrot in windy park (6,4)

I believe the answer is:

karate chop

I'm a little stuck... Click here to teach me more about this clue!

'controlled strike' is the definition.
'karate chop' can be an answer for 'strike' (I've seen this before). I'm unsure of the 'controlled' bit.

'at parrot in windy park' is the wordplay.
'parrot' becomes 'echo' (both can mean to imitate or copy).
'in' means one lot of letters goes inside another.
'windy' indicates an anagram (windy suggests disruption).
'at'+'echo'='atecho'
'park' anagrammed gives 'karp'.
'atecho' put inside 'karp' is 'KARATE CHOP'.

Can you help me to learn more?

(Other definitions for karate chop that I've seen before include "Hit with the side of the hand" , "strike from Japan" .)
