# Element Inspector overlay reference
Use the Element Inspector overlay to configure knots, tangents, and the flow of a spline.
To access the Element Inspector overlay, select knots or tangents on splines in the Scene view.
| **Property** | **Description** |
| :-------------------- | :-------------------------|
| **Knot position** | Set a knot's position. This property is visible only when you select knots. |
| **Knot rotation** | Set a knot's rotation. This property is visible only when you select knots. |
| **Linear** | Select the **[Linear tangent mode](tangent-modes.md#linear-tangent-mode)** for a knot's tangents. |
| **Auto** | Select the **[Auto tangent mode](tangent-modes.md#auto-tangent-mode)** for a knot's tangents. |
| **Bezier** | Select the **[Bezier tangent mode](tangent-modes.md#bezier-tangent-mode)** for a knot's tangents. |
| **Bezier** | Select the **Bezier** mode for a knot's tangents if the knot is in [Bezier tangent mode](tangent-modes.md#bezier-tangent-mode). The following Bezier modes are available:
- [**Mirrored**](tangent-modes.md#mirrored-bezier-mode)
- [**Continuous**](tangent-modes.md#continuous-bezier-mode)
- [**Broken**](tangent-modes.md#broken-bezier-mode)
|
| **In** | Set the magnitude and direction of the knot's **In** tangent. The **In** tangent defines the curvature of the segment that enters the knot. This property is visible only when you select knots. |
| **Out**| Set the magnitude and direction of the knot's **Out** tangent. The **Out** tangent defines the curvature of the segment that exits the knot. This property is visible only when you select knots. |
| **Magnitude** | Set the magnitude of a tangent. A tangent's magnitude determines how much that tangent affects the curvature of its respective segment. A high magnitude value increases a tangent's influence on a segment's curvature and a low value decreases it. This property is visible only when you select tangents. |
| **Direction** | Set the direction that a tangent points to from its knot. This property is visible only when you select tangents. |
