How to lower framerates directly via Keyclone?

Ive heard about this, Can someone explain how to do it?
Thanks. :)

If you click the settings tab, then command editor (in the left hand column), on the right you'll see two boxes maxfpsbk and maxfps. You can start by setting the maxfpsbk to something like 14. That will keep all of your background instances capped at 14 fps. This usually helps a lot.
