Using the up / down arrow keys on my computer I can scroll up / down the service items. This moves the indicator outlined in red below up and down.

Couple of questions:
- I need to press the key twice for the positioning indicator to move. Is this by design and if so why? (I am sure a sure a reference to this on the forums yesterday but I can't find it now)
- What does this actually achieve? I had expected to be able to press Enter when positioned at a particular location and for the current slide projected to be updated. But as far as I can see it doesn't enable me to do anything. Am I missing something?
Thanks, Graham
