If you use a Fusion Table Map, others can see the map if you use a WebViewer and set the url to the url of your fusion table. To find the url needed, bring up the map you want to share on your PC, copy the url of the map display page and use that rul in the WebViewer .
If you want some text, on Screen1 set the alignment to vertical, then all the controls are centered. Just try it.
