I got it to work, and found out the reason why it didn't before. Turns out, the way I have my Mugen input mapped, (wasd) = (up,left,down,right) and (abc) = (1,2,3) on numpad. Because of this, the combination of s+1+2 lowered my screen's brightness instead of doing her grab. I had to put her (abc) to (4,5,6) and then the grab works and functions as intended. Thanks for the solution!
