Press r to show a replay of the fight. You can do this in the middle of any single player game. Press p to pause and play this replay once watching it. Press shift and p to go through replay frame to frame. Press e to continue the fight from the frame you are viewing. This is useful if you want to make a cool replay because if you muck up and fall over you can press r then p and then shift p untill the point before you mucked up and then press e and change the action so it goes better.
I know you didn't ask about this but it is probably the best piece of advice for a beginner which I can give so I thought I might as well give it.
I hope this helps. Welcome to toribash. If you have any other computer based skills (as in digital art, computer created music, animation or video editing) you can use them to make tori credits probably or just become well known in the forum. Such talents are generally highly valued by the toribash community so I would advise you throw yourself into the forums and see what you can get out of it. (But always read the forum rules of every section before posting or you will be told off or given an infraction which is bad).
