I think the names is a bug - rather, it appears to be intended to display a banner indicating dominion, gold income, and resources for each province. Presumably if a player wants the province names on, they'd turn the filter on - the current behavior really clutters up the map display with no way to avoid it. And yes, it really probably should be on a different key, since Tab hides researchers when issuing orders / army setup, then goes schizo in the map display.
