# Manage and inspect variables

In the **Variables** tab, you can [add](ref:add) variables and [manage](#manage-variables) existing variables. You can also [inspect](#inspect-variables) variables to identify any dependencies between them. <!--whether a variable is being referenced (or used) in other variables or dashboard.-->

## Manage variables

You can take the following actions in the **Variables** tab:

- **Move** - Move a variable up or down the list using drag and drop.
- **Clone** - Clone a variable by clicking the clone icon in the set of icons on the right. This creates a copy of the variable with the name of the original variable prefixed with `copy_of_`.
- **Delete** - Delete a variable by clicking the trash icon in the set of icons on the right.

## Inspect variables

In addition to [managing variables](#manage-variables), the **Variables** tab lets you easily identify whether variables have any dependencies. To check, click **Show dependencies** at the bottom of the list, which opens the dependencies diagram:

<!-- Update and comment this back in when the reference functionality is working again

The variables page lets you easily identify whether a variable is being referenced (or used) in other variables or dashboard. In addition, you can also [add](ref:add) and [manage variables](#manage-variables) on this page.
