It's a collection of easily navigated and organized lists of URLs, much like Bookmarks or Favorites on steroids. It's easily modified and even imports existing Netscape or IE lists when you install the Opera browser. Indeed, Opera was designed with the disabled in mind. One might assume that a mouse might be the ideal input device for someone with limited use of their hands or feet, but keyboard commands are much easier to emulate with voice or other command software. Unlike all other major browsers, every action in Opera can be performed using keyboard commands, making it accessible even to those whose use of their limbs is severely limited or non-existent.
Opera also includes event-driven sounds.
Sounds can be configured to play when a document loads or fails to load, for example. As if this weren't enough, Opera Software works continually with developers of software for the disabled to make sure their products are interoperable. Not only is the extremely customizable interface designed to make it easier to use with a variety of these products, but non-disabled users benefit by being able to adapt it to the way they work as well. Security and privacy Opera has taken security and privacy very seriously. Opera offers support for SSL 2.0 and 3.0 plus TLS 1.0 with 128-bit encryption.
