I want to know whether there exists such a Chrome extension that when I select some words and right click on it, the context menu shows all DEFINED search engines in Manage Search Engines of Chrome's Settings which are available in the omnibox. Then I can choose one of the defined search engine to search the selected keywords.
I've checked some extensions, including Context Menu Search, Simple = Select + Search, and Multi-Search. They unfortunately don't suit my requirements because they ask me to define search engines AGAIN and cannot retrieve the ones defined in Chrome! We, programmers, do not like repeatting ourselves, do we?
