A linguistic interface for browsers.
iShell is a browser add-on available by the Ctrl+Space key combination that lets you give commands to a browser by entering text into a special input box. Commands are shortcuts for things that you commonly do on the Web; they can eliminate repetitive tasks and let you get more done, faster. You can instantly obtain interactive results of command execution in the same window. It is possible to create your own iShell commands in JavaScript.
iShell is a descendant of Mozilla Ubiquity project. See more at the extension home page.
IMPORTANT: to use the Ctrl+Space keyboard shortcut, it may be necessary to manually reassign it in the Chrome add-on management console and restart the browser. The keyboard shortcut configuration is available through the chrome://extensions/shortcuts URL.
