The feature you notice first after installing Opera is a menu or "hotlist" that serves as both a directory to the Web and a bookmark file. The hotlist can be easily removed and you can use the full viewing space to look at multiple Web sites at the same time, either tiling or cascading the windows. You can choose to have the sites you were last looking at restored the next time you open the Opera browser. Opera offers keyboard as well as mouse control of its features. Plug-ins such as RealAudio, RealVideo, and Shockwave can be added. Opera does not support Active-X or Visual Basic.
Opera began in 1994 as a research project for the national phone company in Norway, Telenor. It is now on its 9th version. Opera is free for download to all supported platforms. Opera is the browser for Nintendo's Wii gaming console.
