# Editors
Editors are always displayed in the central editor area and tied to an edited resource, for example a SNOMED CT concept or reference set. Any number of editors can be open at once, but only one can be active at a time.
Tabs at the top of the editor area show the name of the resource that is currently open for editing, the icons indicate what kind of resource is edited. The icons symbolize the following resource types e.g.:
* 
SNOMED CT
*  ICD-10-UK
*  OPCS-4
*  NICIP
*  Reference Sets
*  Local Code Systems
If there isn't enough space to display all active editors, the number of hidden editors will be indicated at the top of the editor area as **`>> 1`**.
{% hint style="info" %}
Clicking the **`>>`** symbol will bring up the list of open editors, highlighting the hidden one.
{% endhint %}
{% hint style="info" %}
Clicking one of the editor tabs from the list will activate the selected editor.
{% endhint %}
{% hint style="info" %}
An asterisk **`*`** next to the editor title indicates that an editor has unsaved changes.
{% endhint %}
Some editors contain multiple pages; you can switch between them by clicking on the tabs at the bottom of the editor.
{% hint style="info" %}
To maximize the editor, simply double-click its tab; double-click it again, to bring it back to its original size.
{% endhint %}

## 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/introduction/user-interface/editors.md?ask=&goal=
```
`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.
