Remove unwanted web searches from Just Type [webOS 2.x & 3.x] 5

This tip is only for devices running webOS 2.0 and higher

When you visit a site that uses the Open Search protocol on its site, you will get a dashboard notification letting you add that site to a Just Type search. After a while, that list can grow quite large and probably contains many sites that you are obviously not interested in adding to Just Type. While you are unable to selectively remove these sites from the list of available searches, you can wipe them all out by clearing your Browser History. To accomplish this, open up the web browser app, swipe down from the top-left to access the Web Application drop-down menu, select "Preferences" and the tap the "Clear History" button. If you then re-check your Just Type preferences, you will see that all the non-active website searches have been removed from the list of available searches. Unfortunately, this will also clear your browsing history, but at least it will clean up your Just Type preferences, too!
