Well, that's easy to do in Chrome too. Just right-click and select Search Google For <Word>. By default, no other web site (or URL) is offered. However, by adding the Context Menu Search extension, we can add multiple alternate search engines.
- To do this, visit the Chrome Web Store and search for "context menu search"
- When you get the search results, you'll see "Context Menu Search from ashutoshdwivedi.com" at the top of the list.
- Click Add to Chrome and follow the instructions to add the extension
- Manage your extensions by clicking Extensions in the Tools menu, and then clicking Options for Context Menu Search (or, click on a highlighted word in your browser, right-click, select Context Menu Search, and then Options)
- On the Options screen, use the fields to add a new search. For example, to set-up Visuwords to do a graphical dictionary/thesaurus look-up, specify "Visuwords" as the display name and "www.visuwords.com/TESTSEARCH" as the link
And there you have it. You can now highlight words and then search for them with specific search engines and URLs. The ability to do this for Visuwords and Wikipedia is very useful.
