+| Action | Description |
+| ------ | ----------- |
+| datatype | The `node1` symbol of theis pattern edge is a property class. |
+| equal_to | The `node2` value or field value in the data edge is a number that equals one of the `node2` numbers in the pattern edge(s). |
+| equal_to_date | The `node2` value or field value in the data edge is a date that equals one of the `node2` dates in the pattern edge(s). |
+| field_blank | The selected field is blank. |
+| field_name | The `node2` symbol in the pattern edge is a field name selector. May be repeated (or `node2` may contain a list if permitted). |
+| field_not_blank | The selected field is not blank. |
+| field_not_pattern | The selected field does not matcn the pattern in the pattern edge `node2` value. |
+| field_not_values | The value of the field is not the same as the value in the pattern edge `node2`. May be repeated (or `node2` may contain a list if permitted).|
+| field_pattern | The selected field matches the pattern in the pattern edge `node2` value. |
+| field_values | The value of the field is the same as the value in the pattern edge `node2`. May be repeated (or `node2` may contain a list if permitted). |
+| greater_than | The `node2` value or field value in the data edge is a number that is greated than the `node2` number in the pattern edge. |
+| greater_than_date | The `node2` value or field value in the data edge is a date that is greated than the `node2` number in the pattern edge.|
