**Save:** Saves the data entered into this module, creates a report (which can be printed at a later time), and keeps the module open for further editing.
**Save & Close:** Saves the data entered into this module, creates a report (which can be printed at a later time), closes the module, and returns to the Project Manager.
**Cancel:** Cancels all changes made to this module since the last save, closes the module without saving, and returns to the Project Manager. If this calculation module was just Added to the project, and if it was never saved, then this option will cause the calculation to be removed without saving.
**Copy & Open / Clone:** Uses the current calculation data to create an identical new calculation item in the Project Manager.
**Print:** Opens the Print Previewer where the report can be set up, previewed, printed to a printer, or printed to PDF.

## 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/onboarding/program-overview/interface-navigation/general-calculation-screen-usa.md?ask=&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.
