It's TMBWidget: This Might Be A Widget! This is a dashboard widget for anyone using a Mac with OS X 10.4 or higher. The use is quite simple: access the dashboard (through F4 or other key), click in the text box, type what you're searching for, hit return, and a new browser window in your default browser will open up with the result!
Download and installation
You can download it here.
Once downloaded, you should have a file named "tmbw.wdgt.zip" on your desktop. Double click to unzip, and you should have another file called tmbw.wdgt. Then simply double click that, and dashboard will ask you if you want to install it. Say yes, and you're good to go!
