For navigating around locations, use Radialwalk mixed with symbol finding as failsafes...
As for the trading, it would be quite hard to be honest. SCAR would lag immensely if it had to search for all those text bitmaps.
It wouldn't be too easy to detect text in the chat window, because in world 16 there's a tonne of people talking at once and SCAR isn't fast enough to catch it all.
Time for some people's brains to start working
