+When a trigger is fired, it produces data, which is passed to the ActionHandler.
+Below the `inputs` parameter contains the data from the fired trigger:
+
+```groovy
+import org.openhab.core.config.core.Configuration
+import org.openhab.core.automation.module.script.rulesupport.shared.simple.SimpleRule
+import org.openhab.core.automation.*
+scriptExtension.importPreset("RuleSupport")

+        .withConfiguration(new Configuration([cronExpression: "* * * 25 * *"])).build()
+    ]
+})
+```
+
+When `trig1` fires, inputs.get("module") is `"trig1"`.
+The table below `core.ItemStateChangeTrigger` shows that five keys and values will be inserted into `inputs`.
+The values are inserted twice: once with the trigger id prefix followed by dot in the key, once without.
+That is, `inputs` will have eleven keys and six values: `inputs.get("module")`, `inputs.get("oldState") == inputs.get("trig1.oldState")`, `inputs.get("newState") == inputs.get("trig1.newState")`, `inputs.get("lastStateUpdate") == inputs.get("trig1.lastStateUpdate")`, `inputs.get("lastStateChange") == inputs.get("trig1.lastStateChange")` and `inputs.get("event") == inputs.get("trig1.event")`.
