Aiming up and down in Blood and other Build Engine games

So I picked up Blood and there is a way to aim up and down using the keyboard, but I can’t figure out how to map those to moving the mouse up and down. I know that it won’t help with aiming or anything but I’d still like to be able to do it. I assume there’s shortcuts for “mouse up” and “mouse down” like there are shortcuts for the other keys to use in the config file but I don’t know what they would be and Google doesn’t bring much up.

Edit: Never mind, seems I wasn’t searching for the right thing. In settings there a Digital Mouse Movement section where you can set normal keyboard actions to mouse movement.
