    [[FullSearch]]
        displays a search dialog, as it always did

    [[FullSearch()]]
        does the same as clicking on the page title, only that
        the result is embedded into the page (note the "()" after
        the macro name, which is an empty argument list)

    [[FullSearch('HelpContents')]]
        embeds a search result into a page, as if you entered
        "HelpContents" into the search dialog
