“toggle comments” code from 1.1.3 – where?

Hey Folks, just installed the latest version and liked the “toggle comments” functionality pretty good. I’d like to use it in an older version of the theme.

Is there a way to simply copy&paste some code to the P2 themes first version to have a “toggle comments” button in there?

Couldn’t figure it out by myself – somebody knows a hint? 🙂

[Edit:] Oh, wait, it seems this post didn’t hit the right place. I initially wanted it to be in the P2 Subforum O_o
