Key component of puttanesca, perhaps (6)
I believe the answer is:
escape
'key' is the definition.
(key on a keyboard)
'component of puttanesca perhaps' is the wordplay.
'component of' indicates the answer is hidden within the clue (I've seen this in other clues).
'ESCAPE' is hidden in the letters of 'puttanesca perhaps'.
(Other definitions for escape that I've seen before include "Get free from captivity" , "Leak; avoid" , "it was great for Steve McQueen!" , "Elude, dodge" , "A key at top, on left" .)
