I'm wondering what the keyboard controls are for player reactions after they've won/lost a point. It seems that the only controls for the reactions are 'command' + 'up/down/left/right'. This limits to 4 reactions for points won and 4 for points lost. However, I've seen CPU players show different reactions, such as a fist pump with a raised leg, etc. What are the commands for these? Do I need to change the defaults?
