The $ prefix is used to differentiate parameters used by the widget itself as compared to parameters without the $, which are simply "passed through" to the specific macro or action being invoked by the widget. For most widgets (except $macrocall and $action-xxx), the parameters do not have the $ prefix. -e -- You received this message because you are subscribed to the Google Groups "TiddlyWiki" group.
