| Name | The key’s name. |
| AllowDups | Indicates whether duplicate keys are allowed (true if they are). |
| AllowModify | Indicates whether a key is modifiable (true if it is). |
| ReverseOrder | The key’s order (true for reverse, false for forward). |
| KeySegments | The key’s segments, if any are defined for the key. Returned in an array. |
