Tokens and Mist [duplicate]

Question

This question already has an answer here:

• What's the minimum token contract interface to be showed in mist? 1 answer

Is there a certain set of functions and variables that a Token contract has to implement so Mist can handle the Token display?

In the Crowdsale example Tokens are used. But there is no interface implemented in the token contact. If I "watch" the token in Mist, how does Mist know where to take the inofmation about the token from? All token-balance information is just held within the token contract.

What if I change the name of function transfer to transfer123, will it still work?
