# Drill-ins
> When working in a model, you might find yourself asking: What contributes to this line? Where does this number come from? Drill-ins (currently in beta) allow you to explore these relationships, showing exactly how your numbers connect throughout your model.
## How to use drill-ins
To drill into a driver in a **driver table**:
* Press `Cmd/Ctrl + Enter` to toggle the drill-in state.
* Or, right-click the **driver name** and select **Drill in**.
* Or, hover over the driver name and click the **toggle caret** that appears.
Once expanded, the driver’s **inputs** (based on its formulas) will be displayed **indented inline**.
* A **gray keyline** indicates the input comes from **actuals formulas**.
* A **blue keyline** indicates the input comes from **forecast formulas**.
To collapse a drill-in:
* Click the **toggle caret** on the expanded driver.
* Press `Cmd/Ctrl + Enter` on the root expanded driver.
* Press `Cmd/Ctrl + Option/Alt + Enter` on a **striped input line** to collapse its parent.
Drill-ins **support multiple levels** of depth—expand an input line further to see its underlying dependencies.
## Drill-ins permissions
Drill-ins **follow the same permissions** as the **driver detail pane**:
* **Admins** → Can drill in freely across the entire model.
* **Managers & Members** → Can see **direct (first-level) inputs** but cannot drill further into drivers they **don’t have access to**.
* **Guests** → Cannot use drill-ins.
For a full breakdown of roles and permissions, see this guide.
## Important notes
### Drill-ins are saved per user
* Expanding drill-ins **only affects your own view**—others won’t see the expanded state unless they do it themselves.
* This allows multiple users to explore without disrupting each other’s workflow.
* We’re considering ways to **share drill-in states**, so let us know if this would be useful.
### Want others to see a breakdown?
If you want other users to view the same expansion:
1. **Guide them** to use the drill-in feature themselves
2. **Explicitly add** selected drill-in drivers to the block:
* Select the expanded drill-in drivers
* Press `Cmd/Ctrl + Shift + B` or **right-click** → **Add to block**
This will make those driver lines **visible to everyone.**
### Drill-in lines have a striped background
**Stripes indicate drill-in lines** are **dynamically generated** and won’t appear for other users unless expanded.
**Drag-and-drop** to reorder is **not supported** for drill-in lines.
**Undo/redo** is not supported for drill-in lines.
