Mixed responses but continues forward (7,2)
'continues forward' is the definition.
'presses on' can be an answer for 'continues' (I've seen this before). I am not sure about the 'forward' bit.
'mixed responses' is the wordplay.
'mixed' indicates anagramming the letters.
'responses' is an anagram of 'PRESSES ON'.
'but' is the link.
Can you help me to learn more?
(Another definition for presses on that I've seen is "Continues".)
