## Editors FAQ
|
|
|
|
### How do I get the active editor instance?
|
|
|
|
Current select editor(s) can be queried from [`FileEditorManager`](%gh-ic%/platform/analysis-api/src/com/intellij/openapi/fileEditor/FileEditorManager.java).
|
|
|
|
From an [Action's `DataContext`](action_system.md#determining-the-action-context), use [`CommonDataKeys.EDITOR`](%gh-ic%/platform/editor-ui-api/src/com/intellij/openapi/actionSystem/CommonDataKeys.java).
|
|
|
|
For a given PSI Element, use [`PsiEditorUtil.findEditor()`](%gh-ic%/platform/editor-ui-api/src/com/intellij/psi/util/PsiEditorUtil.java)
|
|
|
|
### How do I open an text editor for a "fake" file?
|
|
|
|
Create a [`LightVirtualFile`](%gh-ic%/platform/core-api/src/com/intellij/testFramework/LightVirtualFile.java) with the contents
|
|
and open it via [`FileEditorManager.openFile()`](%gh-ic%/platform/analysis-api/src/com/intellij/openapi/fileEditor/FileEditorManager.java).
