Thank you Eric, That is exactly what I needed, and it works great. I read about the ViewWidget <https://tiddlywiki.com/#ViewWidget> but saw nothing that suggested this. Is there a better place I should be looking for such information, so that I don't keep bothering people here with simple questions?
