NARRATOR: Mapwall island...
Human researcher: I don't want a map. I want an index for a map.
Saurian researcher: Okay... Twenty klicks further east there's a big glyph that translates to "index."
Human researcher: You memorized the visible glyphs?
Saurian researcher: I built an index out of the visible glyphs, and then searched my index for the word "index."
Amphib researcher: It's just like when you use the "Help" function to help you find the "Find" function.
