Over on the Yahoo Search Blog, YQ developer and guru, Reiner Kraft, posts that a new version of the Yahoo Toolbar for Internet Explorer is available and now includes easy access to YQ's contextually-based info and tools. Simply highlight word(s) on any web page (with Yahoo for Toolbar active) and "automagically" an icon appears. Click and run a web search on the highlighted terms, save the highlighted content to My Web, or translate non-English text into English.
Along with YQ technology now being a part of the Yahoo Toolbar for IE, Kraft notes that it's also available as part of latest release of Yahoo Messenger with Voice.
Finally, the Yahoo Toolbar for IE now includes access to the Yahoo Music Engine.
