Qwg

Qwg   noun   \ˈkw-eeg\

A Chrome browser extension that converts the Omnibox (the multi-use URL bar) into a predictive bookmark launcher for the browser, based on a configuration tree that you supply. An additional mode for searching the tree via the context-menu (right-click) is also supported.

In it's simplest form, Qwg can be used to launch public webpages with content based on the inputted query (e.g. for search engines other than Google). A more realistic (and advanced) real-world example would be to use it for consistently presented access to URL-based services in multiple development environments (dev/test/prod).
