Trim work contents work in computer review (4)
I believe the answer is:
crop
'trim' is the definition.
(synonyms)
'work contents work in computer review' is the wordplay.
'work contents' becomes 'or' (I can't explain this - if you can you should give a lot more credence to this answer).
'work in' indicates putting letters inside.
'computer' becomes 'PC' (personal computer).
'review' says the letters should be written in reverse.
'or' going within 'pc' is 'porc'.
'porc' in reverse letter order is 'CROP'.
Can you help me to learn more?
(Other definitions for crop that I've seen before include "Line (of mountains)" , "Yield from a single growing season" , "Plant grown commercially" , "Harvest or kind of whip" , "Set" .)
