While surfing, the problem of forgetting the entire URL happens very often. What do I do in such a circumstance?

Whenever you begin typing a URL in the address box of the Internet Explorer, it attempts to find a recently visited page that matches the
URL of the web site that you are typing. If it finds a match, it automatically fills in the rest of the addressfor you.

Apart from saving the effort of typing the complete URL, this feature also comes in handy when you seem to have forgotten the entire URL and remember only just a part of it. To enable the "AutoComplete" feature: Open the Internet Explorer and go to "Tools | Internet Options | Advanced". Scroll down and select the "Use Inline AutoComplete" feature that is placed under the "Browsing" category.
