Super questions

So i am trying to pick up cvs2. I am wondering how people are able to use special moves in the middle of supers. lighting legs with chun shoryu with sagat that kinda thing. I was wondering if there is a special input i need to do , jump cancel that kinda thing. Also while i am at it if someone could point me to a list of all the differences in grooves that would be great.

That sort of super cancel is only available for C groove and only from level 2 supers. There is no special command, just input the special or super during the cancel window of a level 2.

As for groove differences, check out buktooth’s system guide. It’s a long read, but it has most all the information on the CvS2 system you could care to know.
