Ok, receiver remotes have keys assigned to switching (on the receiver) between different component inputs (i.e., CD, tape, DVD). How do you do this with the 15-1994?

If I hit CD, then it will change to control the CD player and not the receiver. If I hit VCR then it will control the VCR, not the receiver.

Do you program the main selection keys (at the top) to switch the receiver to that component and then control that component?

HELP!
