The available Calculations are listed in the top portion of the dialog (and there will be more as the product matures). These are ENERCALC-created structural engineering calculations that you can use. The lower portion of the dialog lists the available External Items that can be created externally from the ENERCALC software package and then inserted into an ENERCALC Project File. [Click here](/docs/sel-user-manual/calculation-modules/external-items.md) to go to the specific section.

**Copy:** **For the currently highlighted item in the calculation list**, clicking \[**Copy**] creates a new calculation of the same type using all of the information in the current calculation to make the new calculation.

**Edit:** **For the currently highlighted item in the calculation list**, clicking \[**Edit**] opens the calculation for editing.

**Delete:** Deletes the item that is **currently highlighted** in the calculation list. You are prompted to confirm before the deletion is made.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://enercalc.com/docs/sel-user-manual/project-manager/calculation-list/adding-deleting-copying.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
