Abstract: Methods, and associated systems and apparatus, relate to controlling one or more target devices with a controller that has an event table that associates simple (non-command formatted) event identifiers with command-formatted commands that can be triggered by network messages containing one of the event identifiers. In some embodiments, event identifiers may be included in the payload of network messages generated in response to a hyperlink command. In an illustrative example, selecting a hyperlink in an application program may cause a simple event identifier, such as event “3”, to be sent in a network message to a controller. In response, the controller may perform operations to execute commands associated with event “3” in the event table. The operations may be performed in the controller and/or transmitted to the target device.
