set browserpreview= { on | off}

When browserpreview is set to on, which is the default setting, the .htm file generated by File > Save as HTML displays in a browser. The .htm file will not display unless you also have a file association for .htm files, the browser path preference specified in Tools > Preferences > File Locations, or the path specified by the set browserpath command.

When set to on, browserpreview also selects the View HTML option in the publish dialog boxes.

The default setting is on.
