No parameter.

Opens in the Web browser the reference documentation of the explicitly or implicitly selected element.

For this command to work, a property in XMLmind XML Editor - Configuration and Deployment called "Configuration_Name elementReference" must have been defined in the XXE configuration file. This property specifies one or more reference manual locations separated by whitespace. A location is an absolute URL which must reference the %{local-name} variable. This variable is substituted with the local name of the selected element prior to invoking the Web browser in order to open the reference manual.
