You can use either the Diigo toolbar or bookmarklets, a tiny bookmark
applet, to save annotated Web pages without interrupting your Web surfing. If
you install the toolbar for either Internet Explorer, Firefox, or the Flock beta
browser, whenever you right-click the mouse or highlight something on a Web
page, a menu pops up with options to bookmark, forward, search for, or blog
about selected content. The toolbar drop-down menu scours four major search
engines, as well as within blogs, mapping, news, music, TV, shopping, and
reference engines. Choose the Diigo toolbar's Options menu to set privacy
preferences.
