Hi Luke,
We can gather all of the ObjectStore keys with
keys = [str(j).split(',')[0][1:] for _, j in enumerate(qb.ObjectStore.GetEnumerator())]
See the attached notebook for reference.

Thanks, I ended up just saving my value as a dictionary and then reading and adding to it. So there only needs to be one key. I'll keep this in mind though as this way will have more uses if I use ObjectStore again.

Hi Luke,
We've also opened a GitHub Issue to add a `.Keys` attribute to the ObjectStore. Subscribe to our progress here.
