*''variables'' - \define, <<.wlink SetWidget>>, <<.wlink LetWidget>>, <<.wlink VarsWidget>>, \procedure, \widget, \function all create variables. If the same name is used, then later define will overwrite earlier defined
*''<<.op function>> filter operator parameter'' - only variables defined using \function can be called using the <<.olink function>> operator
*''filter operators'' - only the [[javascript defined filter operators|Filter Operators]] and variables defined using \function with name containing a dot can be called
*''widgets'' - variables defined using \widget can be invoked using `<$widget/>` syntax ONLY if the name starts a dollar sign (to override existing javascript defined widgets) or double dollar sign (to define [[custom widgets|Custom Widgets]]). Without the dollar sign prefix, defining variables using \widget is no different than using \procedure.
*''widgets'' - variables defined using \widget can be invoked using `<$widget/>` syntax ONLY if the name starts a dollar sign. Without the dollar sign prefix, defining variables using \widget is no different than using \procedure.
