# Variable viewer

Use the Variable viewer tool to explore the variables and their values used in your notebook.

> **Note:**
> You cannot use the tool if you have [view access](collaboration.html) to the notebook.

Procedure: View notebook variables

1. Press `Alt+Shift+Enter` (Windows), `⌥ ⇧ Enter` (macOS) to run the notebook.

2. Open the variable viewer by clicking the icon on the left-side sidebar or selecting Variable viewer under Tools from the main menu.

3. Explore the list. You can click any item to view the attributes, methods, and built-in functions for each variable.

> **Note:**
> The variable viewer works differently with different modes:
>
> * Jupyter mode: global variables are shown. Variables deleted from the code remain in the variable viewer until the next kernel restart or their explicit deletion (with the `del` keyword).
>
> * Reactive mode: cell scope variables are shown. Variables deleted from the code are not shown after the next recalculation.
