You can quickly bookmark any Web page by pressing the CTRL key and the D key at the same time. (Don't worry about making the D capital. Just press two keys: the one marked CTRL and the one marked D.)

This nifty little keystroke will bring up your bookmarks or favorites. It works in all the major Internet browsers, including Internet Explorer, Firefox, and Opera. Just go to the page you want to bookmark (the term used in Firefox and Opera) or create as a Favorite (the term used in Internet Explorer) and click CTRL+D and a window will pop up allowing you to save the address for that page and give it a name.
