How do I stop moving an object with default control on?

Hello, well as the title said I have an object with 8 directions behavior and the default control set on, I tried creating an event to stop 8 direction when pressing a key, setting the speed or acceleration to 0, etc; but it still move. Is there a way to make is stop moving without changing the default control?

Thanks

Could you post an image (or the .capx) of your events?

I know that if I change the default controls to no, I can manually assign each movement to a key and then set a key to stop, but is there a way to do that without changing the default control?

To move again use:

Thanks again Seymore
