Paired link events can also be used as “off-page connectors” in order to print a process across multiple pages. Within the process level, they can also be used as generic “go to” objects. There can only be one target link event at any given time. The event marker will be empty when used to “catch” from the source link. The event marker will be filled when used to “throw” to the target link.[1]
