Help with combo confusion

Ok i have been looking at these combos for awhile and i cant figure out what this means “xx”

so i see>c.lp>c.lp>xx>qcf.hp

and this means what?
i know the c.lp=crouch low punch and qcf=quarter circle foward or down foward.

but what is “xx”


Yep it means cancel. As in you are cutting the animation of the move short by inputting a special command to interrupt it and continue your combo further.
Please refer to the Newbie Saikyo Dojo if you have any more of these sort of questions. :tup:
