I believe the answer is:

keep ones hand in

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

'what to do' is the definition.
I know nothing about this answer so I cannot judge whether this works.

'with glove in cold weather to retain skill' is the wordplay.
I cannot quite understand how this works, but
'with' could be 'and' and 'and' is located in the answer.
'in' is found in the answer.
'retain' could be 'keepon' (synonyms) and 'keepon' is located in the answer.
This explanation may well be incorrect...

Can you help me to learn more?

(Other definitions for keep ones hand in that I've seen before include "Detain an employee" , "avoid getting out of practice?" .)
