When using the "Show Text Crawl" Trigger, I can only get it to display a Protoss Themed Text Crawl. I've seen many other maps have Terran or Zerg themed Text Crawls, but I'm not quite sure how to get them. Any advice?
you could use UI layouts to emulate it.

Apparently you need to do some XML editing to do this.
