* Press F7 to show or hide the menu.
* Simply browse through the scene, search for objects, etc, most of it is pretty self-explanatory.

* <i>An overview of the different CppExplorer menus.</i>
### Scene Explorer
* A simple menu which allows you to traverse the Transform heirarchy of the scene.
* Click on a GameObject to set it as the current path, or <b>Inspect</b> it to send it to an Inspector Window.

* Allows you to see the children and components on a GameObject.
* Can use some basic GameObject Controls such as translating and rotating the object, destroy it, clone it, etc.

### Reflection Inspector
* The Reflection Inspector is used for all other supported objects.
* Allows you to inspect Properties, Fields and basic Methods, as well as set primitive values and evaluate primitive methods.
* Can search and filter members for the ones you are interested in.
[![](https://i.imgur.com/Pq127XD.png)](https://i.imgur.com/Pq127XD.png)
### Object Search
* You can search for an `UnityEngine.Object` with the Object Search feature.
* Filter by name, type, etc.
* For GameObjects and Transforms you can filter which scene they are found in too.

### C# REPL console
* A simple C# REPL console, allows you to execute a method body on the fly.

### Inspect-under-mouse
* Press Shift+RMB (Right Mouse Button) while the CppExplorer menu is open to begin Inspect-Under-Mouse.
