+# Using the Azure Cloud Shell editor
+
+Azure Cloud Shell includes an integrated file editor built from the open-source [Monaco Editor](https://github.com/Microsoft/monaco-editor). The Cloud Shell editor supports Monaco features such as language highlighting,

+
+## Opening the editor
+
+For simple file creation and editing, launch the editor by running `code .` in the Cloud Shell terminal. This action opens the editor's file explorer with your active working directory set in the terminal.
+
+To directly open a file for quick editing, run `code <filename>` to open the editor without the file explorer.
+
+To open the editor via UI button, click the `{}` editor icon from the toolbar. This will open the editor and default the file explorer to the `/home/<user>` directory.
+
+## Closing the editor
+
+To close the editor, open the action panel and select `Close editor`.

+
+## Command palette
+
+To launch the command palette use the `F1` key when focus is set on the editor. Opening the command palette can also be done through the action panel.

+
+## Contributing to the Monaco Editor
+
+Language highlight support in the Cloud Shell editor is supported through upstream functionality in the [Monaco Editor](https://github.com/Microsoft/monaco-editor)'s use of Monarch syntax definitions. To learn how to make contributions, read the [Monaco contributor guide](https://github.com/Microsoft/monaco-editor/blob/master/CONTRIBUTING.md).
