Recently visited webpages, collectively known as "history", are stored by Opera so that you can review them later. The simplest point of entry into the browser history is the "Back" button (), but it is not the only one: you can search for webpages in your history based on the time of last visit, or on the content of the page.
To the extent that it is possible, history is cached: to display the cache, type opera:cache into the address field. Depending on the settings in preferences, history items are eventually removed from the list.
History is chronological
To display the global history, type opera:history into the address field. Alternatively, open the history panel (shortcut: Ctrl + 8), where your history is divided into categories: "Today", "Yesterday", "Earlier this week", "Earlier this month", and "Older".
History is searchable
As you are browsing, Opera creates a searchable database of your history, based on the full text content of all visited webpages. To access this database, type a keyword into the address field, or in the "Quick find" field in the history panel. The same information is available from the page opera:historysearch.
Opera includes a special category of history items called "typed history". This category includes only those addresses that have been entered explicitly, as opposed to addresses that were visited via a link. Typed history is accessible by clicking the drop-down arrow on the right side of the address field, or by pressing the down arrow on the keyboard when the address field is in focus. Opera Link enables the sharing of your typed history with other computers and devices.
Remember visited addresses for history and auto-completion
You can specify the maximum number of visited addresses Opera should remember. Please note that a very large history might cause Opera to take longer to start up.
To delete the global history, press.
