That's brilliant thanks.

As yet I've not programmed macro commands, prefering instead to rely on my existing programming method of "linking" most commonly used devices to each other screen by screen. Using electronic Scart switch boxes which can be set to auto-sense or controlling them from my RC5200, does away with the need for fancy macros and keeps things simple given my rather large collection of devices - even my significant other can use it with no probs! - hope she doesn't see this though or my programming days will be over lol.

I appreciate the explanation though.
