 The `*` indicates that every value applies. For example, if `sec` is set to `*`, then every second will trigger execution.
 The `/` indicates increments. For example, if `sec` is set to `0/15`, then starting at `0`, the trigger will be executed every 15 seconds.
-The `,` separates values. For example, if `sec` is set to `2,8`, then the trigger will execute only on the 2nd and 8th seconds of every minute.
+The `,` indicates a list of values. For example, if `sec` is set to `2,8`, then the trigger will execute only on the 2nd and 8th seconds of every minute.
 The `-` indicates range. For example, if the `sec` is set to `5-10`, then the trigger will execute only on the 5th, 6th, 7th, 8th, 9th, and 10th seconds of each minute.
 The `0` indicates no execution. If the `sec` is set to `0`, then the trigger can only execute on higher field values such as `min`, `hour`, etc. The lowest second increment is 60 (one minute).
