After userform entry require tab entry

How do I get a Tab entry-click after a successful entry of userform data so that the next entry set is ready to be started?
My userform has a ListBox with associated TextBox that provides filtering of the ListBox entries, along with other data points to be entered.
I have my start TextBox as Tabindex 0 and my Enter CommandButton as the highest Tabindex, so all it needs is a Tab entry but I would prefer other users to not need to do this when starting the next set.
Attempting to record a Tab click doesn't show me what it needs and I can't find it in other forum posts.
