Continue, keep going (5,2)
I believe the answer is:
carry on
This clue is a double definition.
'continue' is the first definition.
(carry on can mean to continue or keep going)
'keep going' is the second definition.
(I've seen this before)
(Other definitions for carry on that I've seen before include "kind of case one handles personally" , "in-flight baggage" , "Continue - make a fuss" , "Keep going!" , "Display of fussing" .)
