The graphical control element address bar (also location bar or URL bar) shows the current URL and accepts a typed URL that navigates the user to a chosen website in a web browser. In a file browser it serves the same purpose of navigation but through the file-system hierarchy. Many address bars offer features like autocomplete and a list of suggestions while the address is being typed in. This auto-completion feature bases its suggestions on the browser's history. Some browsers have keyboard shortcuts to auto-complete an address. These are generally configured by the user on a case-by-case basis. Address bars have been a feature of web browsers since NCSA Mosaic. == Features == For websites using a favicon (a small icon that represents the website), a small icon will generally be present within the address bar, or somewhere nearby. Favicons are specific to websites, thus a generic icon will be displayed if not specified. The address bar is also used, in some browsers, to show the security status of a web page. Various colors and padlock icons may appear if the page is encrypted, and/or to indicate if intended communication is trustworthy and secure. Some browsers address bars can be used to detect web feeds that can be used to subscribe to pages. The detection of a feed is normally indicated by the RSS icon "16px". A variety of other icons may also be present in the address bar if included with a browser extension. Web browsers often include a feature called Smart Bookmarks. In this feature, the user sets a command that allows for a function (such as searching, editing, or posting) of a website to be expedited. Then, a keyword or term associated with the command is typed into the address bar followed by entering the term afterwards or selecting the command from a list. Quick searches can also be performed in some browsers by entering a shortcut and search terms in lieu of a URL. For example, by associating the shortcut "w" with Wikipedia, "w cake" can be entered into the address bar to navigate directly to the Wikipedia article for cake. This feature is available in Firefox, Opera and Google Chrome. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「address bar」の詳細全文を読む スポンサード リンク
