Search directly in address field
By prefixing search terms by the search engine's shortcut keyword, for example "g" for Google, as in "g Medium-Screen Rendering", you can perform searches directly from the address field.
Opera lets the user control whether Web sites can use pop-ups. Select to block them all, or let the browser open only pop-ups that you have requested.
In Opera's e-mail client, the full text of messages are indexed to allow for speedy searches. There is a built-in spam filter that learns as you add and remove messages. Starting with Opera 7.50, you can use Opera Mail to read RSS newsfeeds. Opera Mail also handles Usenet newsgroups. Read more
You can now use Opera to connect to IRC servers and chat in rooms or privately, send files to other users, and so forth. The chat panel lists previously visited chat rooms and contacts that are on line.
Opera lets you save a collection of open pages as a session, allowing for retrieval on later start-ups, or in the middle of another session. Opera can also be set up to start with the pages you had open when the browser was last closed.
Multiple ******** Interface
Opera is by default a Multiple ******** Interface application, displaying multiple pages in the same application window, allowing you to resize and pose pages next to each other. However, Opera can also be made to work as a Single ******** Interface application, a tabbed application, or with a combination of the Multiple and Single ******** Interface, running multiple instances and windows at the same time.
The entire Opera user interface can be changed by a couple of clicks of the mouse. In addition to the default skins provided, more skins can be downloaded from My Opera. You may also change each skin's color scheme.
Opera supports mouse-movement recognition, allowing users to perform certain movements with their pointing device in order to access commonly used features. These gestures can all be customized.
Opera can automatically analyze the current page and work out the most likely URI for the next page in a sequence, and provides a button for this purpose. For example, when visiting an image gallery with numbered images, clicking the fast forward button will move you to the next image in the sequence.
The Wand password manager
Opera's password manager, the Wand, remembers your usernames and passwords so you will not have to. Log in manually once and use the Wand for later visits to a password-protected Web site.
Zooming in on a Web page is easy using the dropdown on the address bar or the + and - keys. You can also set a default zoom for all pages. Images as well as text on the page will be zoomed.
Press Shift+F11 to display pages as they will be seen on mobile phones and other small-screen devices running Opera. This mode is also useful for making Web pages fit as panels.
