In the Partials Framework you’ll see the same symbols used in a lot of places but without knowing what their generic meaning is it is often hard to work out what they mean in context. I’ll try to provide a list of their generic meanings. Let me know if there are some i’ve missed or if the explanation is wrong.
| Symbol | Meaning |
| ! | Bang / Trigger |
| # | Length / Count |
| $ | Data |
| id | The id of an Event Bus message |
| [] | Index, either position of data item in a message or an array index |
| t | Message type |
| T | Table for message format. See the Splitter component. Defines how the data in a single message can be broken into pieces |
-+ |

+- |

| + | Increment Value |
| ? | Test condition |
| { b } | Event Bus |
| { | Branch to nested loop (chain iterator) |
