| Variables | Input, output, local, and dynamic {variable} names ranked by expected data type |
| Struct & Compound Fields | Member fields after typing . (for example station.cylinder.extended or timer_1.Q) |
| Enum Values | Declared enumeration values (for example Mode.AUTO, Mode.MANUAL) |
| Step References | Local step names (Step10.X) and cross-sequence step states (OtherSeq.Step20.X) |
| Operators & Literals | IEC 61131-3 logical/comparison operators (AND, OR, NOT, ==, <>, <=, >=) and time literals (T#5s, T#100ms) |
