Ever wanted to bookmark a Web page so you can read it later? Here’s a quick way to do it, that works in both IE and Firefox:
CTRL+D
This does not duplicate bookmark entries in IE, but it does duplicate them in Firefox. This means that if you press CTRL + D to bookmark a page in IE twice, there will be only one entry. In Firefox, it will make two entries. And Firefox also has that confirmation dialog to save the bookmark.
