Another "wow" moment from the WWDC keynote: Jobs shows that the System Preferences (control panel) in OS X Tiger knows that "wallpaper" means "desktop picture" and "WiFi" or "802.11" is the same as "Airport," and it highlights the proper Preference Pane to select based on the user's search.

That's smart, but it will be even smarter if Tiger uses this approach system-wide for context-sensitive Help. Users don't really want a good knowledge base to consult when things go wrong -- they want the problem to be instantly diagnosed and fixed for them. The closer a Help system can get to that, the better.
