Expert from university town checking manuscript (12)

I believe the answer is:

proofreading

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

'checking manuscript' is the definition.
'proofreading' can be an answer for 'checking' (proofreading is a kind of checking). I am not certain of the 'manuscript' bit.

'expert from university town' is the wordplay.
'expert' becomes 'pro' (short for professional).
'from' becomes 'of' (of can mean from or belonging to).
'university town' becomes 'reading' (site of the University of Reading).
'pro'+'of'+'reading'='PROOFREADING'

Can you help me to learn more?

(Another definition for proofreading that I've seen is " Checking printed text for errors".)

I've seen this clue in The Times.
