KallOut is a very simple, yet very functional, Windows program. For highlighted text in many programs (including Firefox, Adobe Acrobat, Internet Explorer, Microsoft Office and Notepad) it puts a small icon next to the highlighted words, which looks like this . When you hover your mouse over that icon, it gives you a menu to look up the selected text in many popular services like Google, YouTube, Wikipedia, eBay and many more.
Also with the BestGuessâ„¢ feature, KallOut even analyzes the content you’ve selected and suggests the most relevant places to search for that phrase.
So, if you’ve selected an address, it will suggest Google Maps, Google Street View, and Microsoft Visual Earth. If you selected the name of a famous person, it will suggest their Wikipedia entry. This way, you don’t have to browse through the whole menu of services to find the one you want.
Once you select which site to look up your phrase on, it opens up a floating information palette with your results adjacent to the original content, as shown below.
This floating window stays on top of the original window so you can continue working on your original task while referring to the results that KallOut returned. You can close the pop-up with the X button in the upper right corner, expand the results to a full browser window with the button to the left of the X, and minimize it to the top of the screen with the [-] button (by moving your mouse to the top of the screen, you can access all the KallOut searches you’ve done, or start a new one by clicking the blue KallOut button).
