Opera's strongest points are its speed and multimedia capabilities. Inline support is provided for a wide variety of image, audio, and video formats, including background sounds (MIDI and WAV), Video for Windows (AVI), MPEG Video, animated GIFs, and four different graphic types (JPEG, GIF, XBM and BMP).
Opera steps it up in terms of enhanced HTML features as well. Full tables, frames, and forms support; HTML 2.0 (and most HTML 3.2 commands); Javascript, server push capabilities, and client side image mapping are a sampling of Opera's impressive command of the HTML language.
Integrated mail (send only) and news reading, right mouse button functionality, an extremely helpful status bar, a keyboard interface for single key browsing, multiple concurrent windows support, context sensitive menus, a solid collection of built-in plug-ins, and a number of unique features useful for the physically challenged round out Opera's solid feature-set.
