Snippets versus PickLists ...

Denise, I also meant to clarify that you can still use the PickList feature to accomplish looping/repeat commands, and there will be times when it makes sense to choose that method. It's not "right" or "wrong" to use one over the other. I still have a lot of vintage PickList loops that were originally set up in IT7. It's on my to-do list to convert them to SnippetLoops one day, but they still work fine as is. But the SnippetLoop feature is a new way of repeating simple commands and is a little bit easier to manage, IMO, so when I come up with a new idea for a looping command, SnippetLoop is my go-to option. :)
