change video input with coolsat remote?

[meatballsub]

I have a coolsat universal remote that came with my 5000. I am trying to consolidate remote functions and the coolsat remote works well to control my other devices with one excpetion: I can't seem to find a key to change the video input on the TV, ie I can't change from cable to sat box (video 1) to dvd (video2) when using the coolsat remote in TV mode. Is there a key combo I can use?
