# SNOMED CT Concept Editor

The Concept Editor serves two basic functions:

* You can view detailed information about a concept and its various associated components (e.g. descriptions, relationships, and Reference Set members).
* You can make changes to a concept (e.g. adding another clinical phrase to describe the concept, retiring a concept or description).

{% hint style="info" %}
In case of a SNOMED CT Concept Editor, the title of the editor displays the Preferred Term of the selected concept.
{% endhint %}

The Concept Editor displays information on a series of pages that can be selected by clicking the tabs at the bottom.

When making a change, an asterisk **`*`** appears in front of the editor's title, indicating that you have unsaved changes. Click on the **`Save`** button in the main toolbar to submit your changes to the repository or press `Ctrl`+`S` on your keyboard. Before the changes are saved, a dialog will prompt you to enter a comment describing your change.

## 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.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.b2ihealthcare.com/snow-owl-authoring-platform/editing-and-authoring/snomed-ct-concept-editor.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
