Nope - that is just to help identify "objects that are accessible to Narrator" (which means buttons, labels, text boxes, etc)
Those "commands" mentioned in the article are just a bunch of key combos that activates special features, like highlighting the current Narrator focus, for example.
To be able to use the "Narrator" AFAIK, you need to use standard controls. Using OpenGL/Direct-X and images won't work, at all :/
