## Control at the dashboard level

Use dashboard controls in the upper left to update your dashboard.

### Add a cell

Click **{{< icon "add-cell" >}} Add Cell** to open the Data Explorer and configure a new cell for your dashboard.

For details on using the Data Explorer, see [Explore metrics](/v2.0/visualize-data/explore-metrics/).

### Add a note

1. Click **{{< icon "note" >}} Add Note** to add a note cell to your dashboard.
2. Enter your note in Markdown in the left pane. A preview appears in the right pane.
3. Enable the **Show note when query returns no data** option to show the note only when the query displays no data.
4. Click **Save**.

### Select timezone

Click the timezone dropdown to select a timezone to use for the dashboard. Select either the local time (default) or UTC.

2. Select **Custom Time Range** to enter a custom time range with precision up to nanoseconds.
The default time range is 5 minutes.

### Add variables

Click **Variables** to display variables available for your dashboard. For details, see [Use and manage variables](/v2.0/visualize-data/variables/)

### Presentation mode

Click the fullscreen icon (**{{< icon "fullscreen" >}}**) to enter presentation mode. Presentation mode allows you to view [a dashboard] in full screen, hiding the left and top navigation menus so only the cells appear. This mode might be helpful, for example, for stationary screens dedicated to monitoring visualizations.

### Toggle dark mode and light mode
Click the moon or sun icons to toggle your dashboard between **dark mode** and **light mode.**
