How do I change the controls for the Shrek Super Slam PC game?

In the main menu of this game, when I go to Options, then Control Options, the screen comes up with a page that has Disconnected on the top four times with all of the moves on the bottom. This leads me to believe that people have to connect a game controller in order to change the controls. But the manual for this game says:

“This section outlines game controls using the default keyboard control schemes for Player 1 (Scheme 1) and Player 2 (Scheme 2). These keyboard mappings can be modified in the
Options/Keyboard Config menu.”

But the problem is that when I go to the Options menu, Keyboard Config is nowhere to be found. I’ve already tried contacting Customer Support regarding this issue, but they don’t quite understand what I am trying to get at. They told me to update the drivers for my keyboard and to make sure that a joystick isn’t hooked up to my computer. I don’t even have a joystick. Is there something I can download that will allow me to change the controls for this game? I can only use one of my hands, so I wanted to change the controls so that they are closer to me.
