A Note About Kiosk Mode

Previous versions of Netscape Navigator offered a kiosk mode using a -k switch to open the browser without navigation features so users could be confined to the content displayed. Netscape Communicator replaces this feature with canvas mode, which uses JavaScript to expand your control over the appearance and features of the browser window. See the discussion of Canvas Mode Syntax for more information.
