# References and Links There are many ways that you can link your Issues within Copia, and also perform actionable references. This makes it easy to cross reference your Issue to a PR or commit, and also automatically close or re-open your issue by performing a merge or commit. ## Linking Every issue is assigned an ID, which is preceded by the `#` sign, after the title of the image. This ID can be used to reference the issue in comments and descriptions within Copia. ### Within a Repository A reference to an Issue within the same repository can be created using the simple notation `#123`, where *123* is the ID of the Issue in the same repository. The references will be shown as link to the Issue. ### In another Repository A reference to an Issue within another repository can be created by specifying both the Organization and the repository first, such as `orgname/reponame#123`, where *123* is the ID of the Issue. The references will be shown as link to the Issue. ## Actionable References Copia also supports automatically closing and re-opening an Issue through the use of actionable references. By using the Issue ID, along with certain keywords, the action will be taken. For example, if you enter `closes #123` in the commit message, it will automatically close the corresponding Issue referenced. Below is a list of keywords that can be used. * **Closing**: close, closes, closed, fix, fixes, fixed, resolve, resolves, resolved * **Reopening**: reopen, reopens, reopened In addition, there are a few conditions which must be met: * The commenter must have permission to close or reopen the issue. * The reference is inside a commit message. * The reference is posted as part of the pull request description. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
