# Control a dashboard

This page documents an earlier version of InfluxDB OSS. [InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

#### API token hashing is enabled by default in InfluxDB OSS 2.9.0

Stronger token security: tokens are stored as hashes on disk, so a copy of the database file doesn’t expose usable tokens. Existing tokens are hashed on first startup and the original strings can’t be recovered afterward — **capture any plaintext tokens you still need before you upgrade**.

For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

## Control at the dashboard level

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

### Add a cell

Click **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](/influxdb/v2/visualize-data/explore-metrics/).

### Add a note

1. Click **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**.

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](/influxdb/v2/visualize-data/variables/)

### Presentation mode

Click the fullscreen icon () 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.**
