NCSA Mosaic for the Macintosh User Guide: Advanced Features
You can set up a session of Mosaic to run in kiosk mode. A kiosk is a Web display that restricts the movement of users. This is useful for organizations that want to keep users within a set of files. By removing most menu options, a user cannot, for example, select Open URL... to open another document.
To change to kiosk mode, select Kiosk from the Options menu.
NOTE: You must quit and relaunch Mosaic to change back to normal mode.
