Naruto Ultimate ninja storm 4 keyboard explanation?

I downloaded Naruto Ultimat Ninja storm 4 and I'm now at the point where you can see it in the picture. The problem is that I don't know which key to press on the keyboard for the B key on the XBOX so that I can go to close, and I wanted to ask if someone could tell me which key to press for it.

Should actually be the O Otherwise you can just use a controller.
