lchiu7: Alternatively what you could do is program a macro that did the following.
Bring up input select. That would bring up a list of inputs
Programme the macro to go up a number of times till it hit the top. Then program the macro to go down as many as it takes to reach the right input. Then Enter.
I used to have to do that with a JVC TV.
It would not take much experimentation to get it right. Go up as many times as it takes to hit the top from the bottom input in the list and hope that if you're 3 from the top and you go up, it just does nothing after the 4th up.
Tried this, but unfortunately it didn't stop when it hit the top of the input list, it continued in back to the bottom input. So then when it went forward it ended up on the wrong input. I think I might just have to accept that this particular system is never going to work 100% correctly with activities. Thanks for the suggestion though!
