Blue duo cavorting in capital of Wisconsin (6-1)

Ross

I believe the answer is:

double-u

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

'capital of wisconsin' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'blue duo cavorting' is the wordplay.
'cavorting' indicates an anagram.
'blue'+'duo'='blueduo'
'blueduo' anagrammed gives 'DOUBLE-U'.

'in' is the link.

Can you help me to learn more?

(Another definition for double-u that I've seen is " W".)
