In ffdshow, if I want to crop a video I can press CTRL, ALT, C to do it...how can I disable either one OR both of the activation keys CTRL and ALT, and just set it to work with pressing C (or CTRL C or ALT C)?

The reason I want to do this is so I can use this feature with my ATI Remote Wonder Plus, but it isn't working when I set up the full macro. Please tell me how I can do this task? Someone said I could remove something from the registry, but I have no idea what that means or how to do it.

I'm actually 3 years old, so please be very detailed and clear. Thank you!
