Really dumb general combo question

Hi there, not sure if this is the correct place for this.

I was looking through some things on the wikipedia page and came across some combo listings for SFxT which says: “cr. HP > cr. MK xx Medium SA”

My question is, what does the “xx” mean? I’ve seen this in other combos and I can’t figure it out :s

It means to cancel. Cr. mk cancelled into medium spiral arrow (or whatever SA happens to be).

Doh! I knew it’d be something obvious…Thank you though! :slight_smile:
