working split (for the hams here)

I'm not looking forward to learning how to work split on a new rig, my understanding is that the ft1000mp I'm using now is one of the easiest to use for split. Just hit A=B , tune B however far you need to split and push the tx button above the sub dial. Easy peasy. I just got a FT450, haven't messed with it a lot so not sure how to set it up. Don't really have time at the moment or room for it on the desk. Gotta get off my butt and fix the Tek scope I bought months ago that is collecting dust on the open PC boards. Then I'll have some room.
