`(ui-html-browser BROWSER)`
  Use BROWSER for viewing the HTML-version do manual when the ‘`Manual (HTML)`’ menu item is selected in the ‘`Help`’-menu. If the `(ui-html-browser ...)` command was never executed, then the default is to use the browser stored in the `WEBBROWSER` environment variable. If the environment variable is unset then the default is compile-time dependent.
