Freeze

This extension allows to make cells read-only or frozen.

If a code cell is read-only, it can be executed, but its input cannot be changed. Frozen code cells cannot be either altered or executed.

If a markdown cell is read-only, its input can be viewed by double-clicking on it, but cannot be changed. Frozen markdown cells’ input cannot be viewed by double-clicking.

To change cells’ state, select them and press corresponding button.

Cell’s state is stored in its metadata and is applied to the cell if the extension is loaded.
