About to moan about new trickster (3,3)

I believe the answer is:

con man

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

'trickster' is the definition.
(con man is a kind of trickster)

'about to moan about new' is the wordplay.
'about to' becomes 'c' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'about' indicates anagramming the letters.
'new' becomes 'n'.
'moan' with letters rearranged gives 'onma'.
'c'+'onma'+'n'='CON-MAN'

Can you help me to learn more?

(Other definitions for con man that I've seen before include "A male confidence swindler" , "A persuasive swindler" , "Shark" , "State of NE Africa" , "Modern word for swindler" .)

I've seen this clue in The Mirror.
