New notebook editor (Public Preview)
Databricks is moving the editor used in the Databricks notebook to Monaco, the open source component that powers VS Code. This page describes some of the functionality available with the new editor.
Enable the new editor
To enable the new editor:
Click your username at the top right of the workspace and select User Settings from the drop down.
Click the Editor settings tab.
Toggle the New notebook editor setting.
Autocomplete (IntelliSense support)
When the notebook is connected to a cluster, autocomplete suggestions powered by VS Code IntelliSense automatically appear you type in a cell. Use the up and down arrow keys or your mouse to select a suggestion, and press Tab or Enter to insert the selection into the cell.

Variable inspection
To display information about a variable defined in a notebook, hover your cursor over the variable name.

Code folding
Code folding lets you temporarily hide sections of code. This can be helpful when working with long code blocks because it lets you focus on specific sections of code you are working on.
To hide code, place your cursor at the far left of a cell. Downward-pointing arrows appear at logical points where you can hide a section of code. Click the arrow to hide a code section. Click the arrow again (now pointing to the right) to show the code.

For more details, including keyboard shortcuts, see the VS Code documentation.
