Numbering data items ?

[eno]

I have a movie database that I want to number all the entries so I can put the number on the dvd so I can find them easily.

I need numbers with no gaps in there sequence if possible plus auto numbering would be best

Can the attribute itemID be shown next to an item in data explorer?

Can the itemID be edited?

Or can the itemID be shown by itself as a small window?

Or does anyone have any other ideas or suggestions?

I believe I could do what I want with macro express entering numbers into UR, but would have liked to do it with UR if possible.

As a related issue, I still would also like word excel etc not to steel focus in UR, it is such a nuisance if I want to browse down the data explorer one after the other having to re-focus.
A fix for this would be wonderfull.
