##Get an instance of the active editor
A reference to an instance of the editor can be obtained by calling
CommonDataKeys.EDITOR
To access the editor instance directly the following ways can be used:
* If
[DataContext] (https://github.com/JetBrains/intellij-community/blob/master/platform/editor-ui-api/src/com/intellij/openapi/actionSystem/DataContext.java)
object is available
```final Editor editor = [CommonDataKeys].EDITOR.getData(context);
```
* If
[ActionEvent] (https://github.com/JetBrains/intellij-community/blob/master/platform/editor-ui-api/src/com/intellij/openapi/actionSystem/AnActionEvent.java)
object is available
```final Editor editor = actionEvent.getData(CommonDataKeys.EDITOR);
```
Please see
[EditorIllustration.java] (https://github.com/JetBrains/intellij-sdk/blob/master/code_samples/editor_basics/src/org/jetbrains/plugins/editor/basics/EditorIllustration.java)
for more details.
