Software Overview

Main Features

  • Use mouse gestures to activate shortcuts for quick browsing
  • Control the browser with voice commands
  • Navigate a page with the tab key or the arrow keys using spatial navigation
  • Override CSS with your own styles

Opera is the fourth most popular web browser in the world. It originally included various Internet features such as email capabilities, but is now only used for web browsing. The mobile version, Opera Mini, is available for most mobile devices.

Opera has many features supported by popular browsers but also includes other features to improve your browsing experience. It supports mouse gestures that allow you to create mouse movement shortcuts for commands like "back" and "refresh." It also has improved security features such as a master password that prevents malware from accessing your passwords saved by Opera.

The Opera browser was designed to be accessible to everyone, including people who have physical impairments that may limit their ability to use computers. It gives you the option of controlling the browser with voice commands instead of the mouse or keyboard. It is also the only browser that allows for spatial navigation which lets you change the focus in the page based on an element's location on a page. Instead of just using tab to navigate through the page, you can also use the arrow keys.

Opera is a great alternative to other mainstream browsers, like Chrome or Internet Explorer. If you have a disability that makes browsing the Internet difficult or you are simply looking for a browser that gives you more control, Opera is a great program.
