Are you trying to bind the game movement to other keys? If I am understanding correctly.
In the game click on Options then Controls. (Took the screenshot from the PDF of the game manual which we have in our downloads)
Controls: This is where you can customize your key mappings as well as adjust your settings for the keyboard, joystick, and mouse. Configure Controls: Key configurations are broken down into four sections. Click on Movement, Interaction, View, or Status to view the current key mappings. If you wish to change the key that a particular function is mapped to, 15 just click on the function you want to change and then press the key or button that you wish to use instead. If the key or button you choose is already in use by another function, then that function will become unassigned.
