Inspired by d00heden's post regarding his app "quick event", which lets you add calendar events via global search, (see http://forums.precentral.net/showthread.php?p=1822838) I just figured out how to add keymaps functionality for search engines. Check out: Patch Browser Global Search Addons - WebOS Internals (my new information is at the bottom).

For example, instead of having to type in your search then click on the wikipedia image to do a wikipedia search, you can now just type in "w dinosaurs" and press enter.

I'm also going to see if I can figure out how to tweak this to send SMS's as well. For example you could just type in "bd hello" and it will create an SMS to whoever you assign as "bd" with the message "hello." You might still have to press send, but it would still be useful. That might take awhile but it's the same basic idea.

Enjoy.
