Once Babylon is activated, and you can see the Babylon icon in your system tray, you can use Babylon Tool to search for information with a single click - point your mouse cursor at any word expression or number shown on your screen and click on it using your Babylon configuration. When you click on a word Babylon Find Window will pop-up. When you click on a number, the Babylon Conversion Window will pop-up.
Another way to activate Babylon Tool is to click on any empty space on your screen. This will immediately open the Babylon Search Window. Type in your word, expression, or value in the Search Box. Press "enter" or click go to receive results.
You can view or change Babylon Tool's default settings from Babylon Menu. Right click the blue Babylon icon in the system tray, or click on the "menu" icon from Babylon Tool and choose "configuration".
