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 can I be notified about editor events? Use project-level listener [`FileEditorManagerListener`](%gh-ic%/platform/analysis-api/src/com/intellij/openapi/fileEditor/FileEditorManagerListener.java) or [`FileEditorManagerListener$Before`](%gh-ic%/platform/analysis-api/src/com/intellij/openapi/fileEditor/FileEditorManagerListener.java) to be notified about all file open/closed/selection changed events. ### How can I set a custom editor tab name and tooltip? [`EditorTabTitleProvider`](%gh-ic%/platform/ide-core-impl/src/com/intellij/openapi/fileEditor/impl/EditorTabTitleProvider.kt) registered in allows for specifying custom names and tooltips displayed in the title of editor tabs. If access to indexes is not required, it can be marked [dumb aware](indexing_and_psi_stubs.md#DumbAwareAPI). ### How can I set a custom editor tab background color? [`EditorTabColorProvider`](%gh-ic%/platform/ide-core-impl/src/com/intellij/openapi/fileEditor/impl/EditorTabColorProvider.java) registered in allows for the modification of the background color for specific files. If access to indexes is not required, it can be marked [dumb aware](indexing_and_psi_stubs.md#DumbAwareAPI). ### How do I open a 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).
