Tip:
I use the online dictionary, OneLook, and keep it on my desk top for easy access.
Putting a website on your desktop is easy to do. Go to the website you want, look in the Address box and see that little icon at the beginning of the URL? You need to drag it onto your desktop. To see your desk top, click the Restore Down button (the middle one) in the upper right hand corner on your Title Bar to make the window smaller.
