# Edit a notebook

This page describes common notebook actions, including adding, editing, reordering, and deleting cells, as well as using interactive controls and displaying content.

## Edit modes

There are two edit modes:

* **Command mode**: Perform actions on cells, such as adding, deleting, and moving them.
* **Edit mode**: Modify the contents of a cell.

Press **Escape** (`Esc`) to enter command mode. Press **Enter** (`Enter`) to enter edit mode.

## Add a cell

Notebooks support [Python](#python-cell), [Markdown](#markdown-cell), and [SQL](#sql-cell) cells. Add a cell using the notebook UI or a keyboard shortcut.

    Press **Escape** (`Esc`) to enter command mode, then:

    * Press **A** to create a new cell above the current cell.

## Add interactive controls

Add interactive controls, or widgets, to notebook cells. Use widgets such as sliders, dropdowns, and buttons to update notebook content dynamically.

For example, copy the following code into a cell to create a basic interactive slider:

```python theme={null}
import marimo as mo

slider = mo.ui.slider(1, 10)
mo.md(f"Choose a value: {slider}")
```
