Jumps to an action within a multi line action / macro. You have to use the action name of the target as a jump target. You can jump only to actions within your multi line action / macro. If the label can't be found, an error message will popup. You also could use a short form, where the label is added directly to the string. eg. string="goto label_end"

<action name="goto exit" string="goto" label="End Function"/>
