Ambrosia Software today announced the release of iSeek, a new tool that allows you to instantly search for anything on the Internet, no matter what program you are running at the time. According to the developer, iSeek puts a search field in your Mac OS X menu bar that is “always at your beck and call, needing just a click or keystroke to start your search.” The software comes pre-configured with search shortcuts for several useful Internet resources including Google, Amazon.com, Dictionary.com, Yahoo!, CNN, Reuters, Weather.com, several Mac-related sites, and more. iSeek is US$15 shareware.
