# selectedFrameIndex

> The zero-based index of the frame currently selected in the Profiler Window.

## Definition

* **Type:** Property
* **Namespace:** [UnityEditor](/engine/6000.5/script-reference/unityeditor.md)
* **Assembly:** UnityEditor.CoreModule

```csharp
public long selectedFrameIndex { get; set; }
```

### Remarks

To change the currently selected frame in the Profiler window, set this index to any value between and including [ProfilerWindow.firstAvailableFrameIndex](/engine/6000.5/script-reference/unityeditor/profilerwindow/firstavailableframeindex.md) and [ProfilerWindow.lastAvailableFrameIndex](/engine/6000.5/script-reference/unityeditor/profilerwindow/lastavailableframeindex.md). When this property is set to a value outside of that range, or smaller than 0, Unity will throw an ArgumentOutOfRangeException.

If no frames are shown in the Profiler Window this index will be -1.

Note: Since the Profiler Window shows the current selected frame as a 1 based index, this value will be n-1 of whatever the value the Profiler Window shows.
