                          |   | 3 | Trac supports a convenient way to refer to resources of other Trac servers using Wiki markup. An !InterTrac link can be seen as a scoped [TracLinks TracLink]. It is used for referring to a Trac resource located in another Trac environment. |

                          |   | 7 | Simply use the name of the other Trac environment as a prefix, followed by a colon, ending with the resource located in the other environment: |

                          |   | 13 | The other resource is specified using a regular !TracLink, of any flavor. | 
                  
                          |   | 14 |  | 
                  
                          |   | 15 | That target environment name is either the real name of the environment or an alias.  | 
                  
                          |   | 16 | The aliases are defined in the `trac.ini` file, see below. | 
                  
                          |   | 17 | The prefix is case insensitive. | 
                  
                          |   | 18 |  | 
                  
                          |   | 19 | If the InterTrac link is enclosed in square brackets, like `[th:WikiExtrasPlugin]`, the InterTrac prefix is removed in the displayed link like a normal link resolver would be. For example, the above would be displayed as `WikiExtrasPlugin`. | 
                  
                          |   | 20 |  | 
                  
                          |   | 21 | For convenience, there is also an alternate short-hand form, where an alias can be used as an immediate prefix for the identifier of a ticket, changeset or report, eg `#T234`, `[T1508]`, `[trac 1508]`. |

                          |   | 25 | The only prefix defined by default is `trac`, which points to trac.edgewall.org. Additional prefixes can be specified in the [TracIni#intertrac-section intertrac] section of TracIni. For example: |
