Question about terminology

i was wondering when looking at combos, what is “xx” used to represent?

ex. c.lp xx f.p

It means cancel.

So in your example, you want to hit “f.p” (I assume you mean :hp:) during the recovery frames of c.lp.

I don’t thing you’ll find anything like your example in any combo. A normal chain is not usually represented as normal xx normal. Something like crouch MK. > cancel into HP fireball would be like this: cr. mk xx qcf+hp
